Uh, don't know what I was thinking. There's no flag day in either
of these: as long as either one is installable, things should work.

However, any versioned build dependencies on packages moved into
IO-Compress upstream do get a flag day unless we introduce the new
libio-compress-perl package first.

That's not too bad as it doesn't affect anyone else because the
unbuildable packages stay installable. And it's the "unstable" suite
after all.
