You suppose to know everything, instead you, for justifying your supposition, show examples without considering the real factors (I don't know if because you really don't know, or because you DON'T WANT TO KNOW, otherwise your conspiracy theory cannot survive).
In the period 1995 - 2008 (when there were meetings of Golden League with high budget, TV could broadcast all these meetings live, the interest of newspapers was at the top, and the track meetings were more important than the best Marathons), all the organizers looked for some attempt against WR, for increasing the visibility of their meetings, in order to increase the level of sponsors and the budget for the following year.
In that period, we had the fortune to have several extra-class athletes, with superior talent compared with athletes of the past. That period changed the history of athletics in middle and long distances, because was the beginning of a PROFESSIONAL INTERPRETATION by Kenyan and Ethiopian runners.
The big athletes of the previous era (for example, Kip Keino or Miruts Yifter) didn't have any continuity in their training, because there were very few occasions for competing at high level, AND THERE WAS NO MONEY.
The only real opportunities for Kenyans were Olympics and Commonwealth Games, for Ethiopians Olympics only. So, African athletes had full seasons without any goal, and the best athletes were not in training.
Ethiopians had a big hole in their activity, from 1972 and 1977, because boycotted Montreal OG, and in 1977 and 1979 had the only opportunity of the World Cup (when Yifter dominated both 5000 and 10000). And, after OG 1980 in Moscow (when they won many medals, also because Kenyans were not there), again had to wait till 1988 per having a new opportunity.
Only at the end of the decade '80-'90, in Ethiopia, with dr. Kostre, there was the beginning of a professional way for recruiting athletes and training at high level. In those years, some top runner started to grow with different mentality and different system, like Fita Bayisa, and, among women, Derartu Tulu. Haile was one of the first athletes growing in this new system.
I don't thin Haile was stronger than Yifter, but had an incredible continuity in training, and was the first to have economical advantages from his performances. He was the one giving new mentality to Ethiopian runners, sometimes fighting with the Federation, because had a superior personality, and was the first top Ethiopian working with a manager able to teach how to use the talent not only on the track.
I remember the press conference of Haile after winning 10000m in WCh 1995 in Goteborg. Some journalist asked him : "We know Ethiopian Federation asks to all Ethiopians to give 80% of their prizes in the competition to the Federation itself, otherwise they will not allowed to compete abroad : which is your position in this situation ?", and Haile, still very young but already WR holder with 26'43". answered "I told the Federation exactly the opposite : if I can't have what I win, I don't go to win any medal for my Country. So the right word in this case is "NO"."
In this situation, organizers had big budgets for the pacers, in order to have ALWAYS very fast races. For the first "under 8'" in steeple, run by Moses Kiptanui in Zurich, the last rabbit, Eliud Barngetuny, received 15,000 USD, and also later, for my personal knowledge, when the organizers wanted Shaheen to attack a WR (also if he was not at the moment able to do it), always there was a budget between 12000 and 20000 USD for all the rabbits. The same in the competitions of 1500, 5000 and 10000m, BECAUSE THERE WERE ATHLETES ABLE TO ATTACK THE WR, INTEREST IN DOING IT, AND MONEY ENOUGH FOR ORGANIZING THE COMPETITION WITH THIS GOAL.
This means that ALL the races were always fast, and the best athletes (Morceli before, El Guerrouj after, in 1500m, Bekele in 5000m, Tergat, Haile and Kenenisa himself in 10000m, Kiptanui, Wilson Boit Kipketer, Boulami and Shaheen in steeple) became the rabbits for ALL THE OTHER ATHLETES in their attempts.
When the interest (and the money) around track started to decrease, also due to the economical European situation, there was a migration of the best talents for 5000 and 10000m to road races, since a HM of medium level can give more money than a top track competition (a 4th place in DL pays 3000 USD, and in the competition you indicated in Paris 2012 I had Thomas Longosiwa running 12'49"04 winning 2000 USD !).
If you go to see the list all-time in these events, you can see how all the best performances of the athletes who never won anything (we can consider of "medium-high international level") were achieved in competitions won by one of the stars, with the aid of rabbits for running fast.
The case of Thomas Longosiwa is emblematic : he started with me in 2005 as pacer for his wife (the marathon runner Jennifer Chesinon, 2:31 PB), was in the camp I organized with my personal money (without the help of any manager) for helping young new athletes in Iten (at that time I was the head coach of Qatar for endurance events), and after 3 weeks I saw in him a good talent, I went one Sunday morning with him on the track after his long run together with Jennifer, I asked to run 10 times 500m in 1'20" for testing him, and he ran all the tests in 1'16" with the last in 1'12", so I told him "It's better you look to be yourself an athlete, because you have more talent than your wife". After this, he qualified in the Kenyan Team for Olympics 2008 (finalist), WCh 2011 (6th), Olympics 2012 (bronze), WCh 2013 (4th), and NEVER won any competition, running his fastest times in 2007 (12'51"95, in Bruxelles) and in 2012 (12'49"04, in Paris), in both the case finishing number 5. He ran 10 times under 13', and of sure is not one of the top talents under morphological and physiological point of view, but is one of the best under the MENTAL point of view (and was always TOTALLY CLEAN).
So, you are speaking without considering the real situation, because are obsessed by the idea of doping. You absolutely don't know what a real talent is, and where an athlete can arrive if he's so lucky to have this gift.
Personally, I'm not satisfied of the WR of Shaheen, for example, since I know he could have run under 7'50" with the shape of 2006, if pacing and weather conditions in Zurich were different. I see room of improvement in ALL THE WR of endurance, with the talent of the holders, if they didn't have to face some individual problem, of various nature (injuries, family, continuity in training, etc..). At the same time, I don't think the WR of Kenenisa in 10000m is a great record : he could have run near 26' if in his best seasons REALLY prepared the event (instead, he NEVER prepared 10000m, only 5000m, and in the two occasions he bettered the WR, one time was sick, the other in bad shape !).
Finally, speaking about Kenenisa, we need to consider he lost more than 6 years of his career because of the injury he had in 2009. After that injury, he NEVER used training with spikes and high speed on the track, and of course his best results were only 26'43" in 2011 (after less than two months of training) and 12'55"79 in 5000m (9th in the famous race of Paris 2012).
What his injuries have to do with doping, is something really mysterious.
Sometimes, before speaking about what you don't know, it's better to shut up. Otherwise, who knows the truth can only think of you as an idiot of cosmic size.
