I assume they're saying it's no better than easy pace, since it doesn't fall into one of Daniels' (4?) official paces.
I disagree and think thon pace is ideal tempo pace IF one's legs are tired from heavy mileage, which should be the case for marathon training.
Re OP's question, for the marathon, I view long runs as the key workouts. Speedwork seems mostly irrelevant, though some easy speed sessions might add some nice variety and keep things fresh/interesting.
Nevertheless, the poster typed 'zero benefits' once and 'literally zero benefit' another time. There is only one interpretation to this: running at this pace does not advance fitness. It has exactly the same effect as watching 'Gilligan's Island'. The latter has 'literally zero benefit'. Running at marathon pace is exactly the same. Your fitness will not advance in any way, at all, just like watching TV.
I'm not saying this, the poster in question is. Enough of that. I believe NErunner posted great workouts. Even Canefis, who may have broken up with JS and doesn't seem to reflect the Wizard's philosophy, had some good ideas, with the caveat that the 10k-HM specific sessions can be just maintenance and the longer and more marathon-specific get first priority.
Now, Smoove is a bigger Daniels expert than I and many of us, so he could elaborate further. An M-pace appears in later editions of the Formula. Perhaps it's just the most recent one. In fact, he gives a chart demonstrating a continuum from T-pace (which is often suggested for 20 min. or slightly longer tempos) to slightly slower for a somewhat longer tempo, and it ends at M-pace, at which efforts longer than an hour can be reasonably done.
Anyway, I agree with you, mwh. Long runs of various sorts are the key, with some 'speed' added in maybe, but what a 10k runner would call 'speed work' is low priority and can be occasionally done for variety. In fact, it seems this thread has various good advice with the exception of the poster who seems to believe that only certain paces can benefit the runner. Not only does any running benefit the runner, but marathon pace is of utmost importance when training for your best possible marathon performance.
