Well, in terms of the current spec, PRs are fully specified enough
that a sufficiently informed SA can return PRs for a non-requesting
port on the same node. I've long advocated for an improved PR
mechanism that would be more APM 'aware' and router compatible
(Connected Path Query)
There are a few good ways to get that sort of information into the
SA..
