"Oversight" -- a new user class with only a handful of members -- allows page revisions to be erased without a developer having to dig around in the metaphorical wires.

It's probably necessary (for legal reasons and to protect admins from real-world nuisances), which is a shame; I'm a little worried about the long-term effects of giving anyone that much power. (Short-term, no worries: even assuming the 16 users with oversight were inclined to abuse their power -- a strange assumption -- they're swamped with more minute issues.)
