i'd agree - howver it turns out that we have a code piece
in the HNA input path which rejects any incoming prefixes which we are
advertising on our own - so if you advertise a 0/0 to the outside world
we are blind for remote 0/0 advertisements.

IMO we can remove this check because local HNA routes (read: cost 0)
are always preferred over remote HNA routes.
