No, it doesn't.  And we have at least one extremely important protocol that
needs as many ports as we can give it (DNS).

A blacklist is the way to go, and we already have it.  We just need to fill
it, make it easier to extend (.d directory), tell people about it, and teach
stuff other than SunRPC to use it when necessary.
