This should be OK.  A carp(4) interface is just a place for CARP
settings to live.  No real traffic passes through it.

I seem to recollect that I ran into this issue, too.  Of course,
it's a bug.  CARP apparently caches the old route forever.  It
should track such a change if it doesn't yet.  We have a sort of
notification for the event, don't we?  The userland has the routing
socket for that, but I don't remember about the kernel.

Thank you for paying attention to that!
