Any given use of administrative powers cannot be reverted or reversed by another admin unless the issue is brought to adequate discussion.
This disturbs me a bit. I can think of many legitimate examples where an admin might reverse another admin's action without discussion. I did it just a couple of days ago, for instance, where I undeleted an article that had been incorrectly tagged for speedying and then deleted. I didn't discuss this with the deleting admin (I didn't think it needed discussing, frankly; I did leave a courtesy note explaining what I'd done on his talk page). Was this 'wheel warring'? Under your policy it would get me desysopped.
I agree and have changed this part of the proposal already.
