Thanks.  And thanks for looping Michael in.  I'd appreciate his
input in this area.

I see that you posted a separate message outlining the idea
yesterday and I didn't see any response (and I was sick and lacked
energy to think it through); I think the basic approach to use "an
API to bring set of refs hidden from your normal view" is sensible.
Except for the unfortunate naming of the interface that makes it
sound as if it is only to access submodules, but that is where the
feature original came from, so let's not complain too loudly ;-)
