Similarly, there could be registries of information about B that do not
need to be DID method specific registries.

What we do know is that B on its own is meaningless. There must be other
information associated with B to give it meaning. It is this other
information that A seeks and often (should always?) requires as a
prerequisite to establish a useful relationship with B.

The answer doesn't make this second assumption. The endpoint for talking
with B, for example, could be put in a registry along with the other
information about B for which A might search. Such a registry need not
be associated with a particular DID method and could be contextualized
in some important way for its human and software users. And, of course,
it need not be a duplex.
