From a security standpoint, I think it's definitely better to regard
them as separate protocols. They are certainly separately filtered on
firewalls, and they are often routed differently, too.
That said, I see no reason not to have some sort of easy way of saying,
"listen on all the interfaces you can find using all the protocols you
know." So long as you have the ability to distinguish where you listen
by both protocol and address, it's easy to be as secure as you need to be.
