There's a bzr-gc plugin, and a (I think quite similar) bzr colo-gc
command in bzr-colo.  People also sometimes branch out the parts they
want and leave the repository behind.  So it's not really a straw man
but it is a tangent.

Anyhow, it is a logically possible thing that might be useful in some
cases.  Allowing people to use more of the logically possible
combinations depends on making the user model really clear so they can
reason about them safely, and it is is less important than having a
clear main stream case.  I don't at the moment think reference
repositories ought to be part of the main stream case.
