I always expected this to work on a best-effort basis.  The problem with doing something stronger here is that it blows out the scope.  Badly.  Migration is hard enough when only one endpoint moves, but this would require a lot more complexity and machinery.

Mike labelled this `quicv2`, which is entirely appropriate.  Though it might be OK to define an extension that parallels preferred_address that provides a v4 fallback address.
