That brings the problem that our mirrors are not that closely synced as we
would expect, especially for the port tree. Some mirrors are up to a day
behind the main one, and switching temporarily between those could leave
you in a situation where port versions jump back and forth. I'm not exactly
sure what would happen, but I'd rather not find out the hard way.

We have code that detects this situation and warns users, but aren't using
it to automatically ignore wrong resolve results. This has been discussed
before and there were some strong opinions against fixing this behavior
which isn't our bug and for telling users to shout at their providers for
ignoring the RFC.
