How about providing this minimal amount of mechanism:
a) A way of marking a particular edit as a "milestone."
b) The ability to mark an edit as a milestone would be suitably restricted to people, probably sysops, who would agree to be governed by discussion, consensus, policy, etc. TBD.
Well, the wiki way is more like: make Milestone a category; allow anyone to add, therefore, but have a convention that no one awards their own edit a milestone, and that anyone adding a Milestone category should comment it in the edit, so it's clear in the history. And one can have Milestone2, etc. This is one form of editable page ratings.
And yes, I suppose it would be good to have the chance to see a filtered page history, with just those edits that affected milestones.
