Also, if a particular user's changes are going to be rolled back, this needs to include not only undoing things they added or changed but also undoing deletions.

Basically, the same thing that happened with Ehrlich Road, which was a
single road which I deleted to change into a dual carriageway.

This kind of stuff is going to happen constantly once you start
mass-deleting tens of thousands of accounts.  That's why the deletion
strategy needs to be set long long long before people are required to
decide whether or not to approve the switch.

This is something I've been saying for a long time, but I'm glad it
has finally been shown rather than just said.  The deletion of one
single user who didn't even edit that much, cascades through an entire
map (some of which has been fixed, but y'all have a *lot* more to go).

Maybe the 1,500 year plan is the way to go.  It could always be sped
up as y'all get better at cleaning up from the big mess you're making.
