There is no meaningful distinction, is there?  The only distinctions I can
see are for understanding how they'll work for backwards compatibility,
and "less than 65535" seems adequate for that.

I'm agnostic to which notation we should use, but I don't think it matters
all that much, as long as we avoid confusing ourselves.
