What we do for some transitions is editing the source package a library package
comes from, so that both library revisions (libfoo1 and libfoo2) are considered
eligible to stay in testing at the same time.  This eases the pain of some
transitions.  For that to work in sid, as library removal is manual anyway, you
need to convince ftp-masters not to remove them when there are still quite a
bunch of reverse dependencies.  Given that NBS removals should show the rdeps
too, it'd only be a policy decision.
