This is just dumb in my opinion. Running with a waterfall start change the event.
Maybe they thought having two people share a lane was 'unfair' but that would be much better than this. It's a huge advantage to be in the 3 person outside stagger as you only have to fight two other people at the line and you also are ahead and see where you competitors are when you come off the turn.
