OK, thanks all! Wiki page updated accordingly.

Sharing a thought that crossed my mind: I thought about increasing
the amount of time we wait between steps, from 1 week to say, 2 weeks,
giving anyone about a month to step up. I eventually dropped the idea
because someone stepping up late should easily be able to revert
the removal, particularly now that we've switched to git. In the
meantime, since we suspect no-one is usually going to step up,
waiting longer just defers the corresponding cleanups we want to do.
If you guys agree with that, I'll add something to the wiki page
to explain the thought process.
