I think I wrote this too quickly. co-installability was of course the
reason for the versioned packages (that you suggested to get rid of).
The idea is that upgrades leave behind the old versioned packages (and I
have seen that happening), so you can still compile your programs with
the older versions if you want to. So I don't understand why apt tries
to remove the old packages. Do you know why? Because of course it is
possible that we made some mistake in the dependencies. Or could it be
that this behavior of apt changed sometime in the last years, or that
this behavior depends on an apt option?
