Maybe we should instead consider whether that is an appropriate
location for the registry.

This is a very interesting property from an application perspective,
I'd certainly be disappointed if this were to be pigeon-holed into a
TLS-only thing.

(I'll point out that I tend to think that most, if not all,
application protocols would benefit from exclusively using TLS.  But
that's not a universally shared view :)
