Your suggestions are good for a manual setup where the target repo
doesn't already exist.

But what I was looking for was validation from git.git folks of the idea
of replicating what "git clone -l" does, for an *existing* repo.

For example, I'm assuming that bringing in only the objects -- without
any of the refs pointing to them, making them all dangling objects --
will still allow the optimisation to occur (i.e., git will still say "oh
yeah I have these objects, even if they're dangling so I won't ask for
them from the pusher" and not "oh these are dangling objects; so I don't
recognise them from this perspective -- you'll have to send me those
again").

bringing a new mirror into play, normal repos, wild repos, and on and
on...
