There's been on and off discussion this year about container registratio=
n, not just retrieval.  That could be done as an add-on PSR, most likely=
.  The challenge is that there's fundamentally different ways to go abou=
t registration, and little consensus on it.  (And the people most intere=
sted in talking about it haven't wanted to go to the effort of organizin=
g a Working Group.)  I suspect scoping would have similar challenges.  B=
ut if someone can get a working group together around a particular direc=
tion, we'd be open to that discussion.

That would be entirely off topic for this list, though, so let's not go =
further down that rabbit hole.
