Why not? Wikipedia seems to be living pretty well with that approach 
(yes, I'm aware that there are differences to osm, as the revert button 
of a page only appears on that pages history, not on a "global revert 
list" as it would be in our case).

I've heard this argument many times before, but no prove that it is 
actually true. Why not do it the osm way, implement it the simplest 
possible way and see how far we get?

If the edit can't be reverted because of conflicts, simply show a: 
"can't revert because of editing conflicts" message.

I guess this would already solve 99.99% of all cases.

Well, chicken and egg problem :-)

Yes, if we need to have those ninja mapper group, then this problem appears.
