This could be carried by a sub-TLV of Hello (or a sub-TLV of IHU if you
want to make it per-host).

Not a bad idea, but I'm a little hesitant to implement that, since it
would require defining a taxonomy of interface types at the protocol
level.  (Currently the taxonomy exists in the implementation, but it
doesn't appear in the protocol -- the protocol only knows about metrics.)
