Bugs like T28725 (Bug 26725) should really be something the community can handle itself (given enough consensus).
As I understand it (and there is no guarantee that I do at this point), this involves DNS changes at this point so we'd probably want some way for the old name to resolve for a while.
I'm thinking that it should be possible to get a list of names that the wiki serves and use that to populate, say, a BIND configuration file.
But I leave this here as a place for people to comment and shoot my idea full of holes.
