Thanks for your thoughts. I understand your concerns, and I think it somewhat results from to the fact that MediaWiki groups do not really understand hierarchies - in many cases either you have the ability to do something or you do not, regardless of who or what your target is.

We may have had some special Chat code that overrode this which got disabled or removed in the recent update, and some careful thought will be needed about the best long-term solution, especially since each wiki works differently.
