We do follow removals from Debian where it's possible. The problems are
that sometimes following the removals would break other things (we don't
normally remove packages that return non-empty results from
reverse-depends or seeded-in-ubuntu), and that a number of the relevant
packages were never in Debian to start with - we're still suffering from
the ill-conceived import of debian-multimedia.org way back in 2005 or
so.
I think that good things for somebody to do would be:
* Refactor process-removals in lp:ubuntu-archive-tools so that it can
produce an HTML report of blockages rather than simply acting in
interactive mode (which basically means that only a handful of
archive admins ever see its output)
* Figure out the list of multimedia-related packages in Ubuntu that
were never in Debian, and either get them into Debian or consider
whether they can have removal bugs filed for them in Ubuntu
* Go through the list of removal blockages that are associated with
images, and coordinate with (especially) the Ubuntu Studio team to
update their seeds

All other things being equal it's probably helpful to do them in the
same order. I've already done about 20% of the required rebuilds for
Perl and should be able to blast through the rest today (especially now
that all the powerpc builders are fast, yay), so I think I can be out of
your way in time.
