I think in the medium term there must be a way to clean out unused
(unreferenced?) revisions in a shared repo. Simply in terms of space
you need to be able to do it, otherwise over time your repo will fill
up with lots of junk. And there might be people who have a legal
requirement that all code from branch x is physically removed.
