well, if foo.bar decides to have the DNS name pointed to
IP address of a server which doesn't know about it, that
seems to me foo.bar's problem and I'm happy to leave it
there.

I don't see issues if the domain names are condigured in reasonable
administrative context though.

Well I don't like the domain names in route header either, but I think the
question is how to deal with client that use it -- drop them on the floor?

I think configuring those domains using the domain module would work just 
fine, only if the rr-module would leverage it :-) I think that should be
addressed. Sounds like something that should be filed on JIRA.
