If policy (or their implementation in dpkg) really makes us ship useless
files, that's is really stupid.
I will take a few hours early next week (or perhaps even this week) and
do some upgrade tests for all paths (cyrus21->cyrus-2.2,
cyrus21->cyrus22->cyrus-2.2, cyrus22->cyrus-2.2) and see what our
current setup results in. If we get the results we want (i.e. old
packages disappear with no orphaned files), I suggest we leave it as is.
If we don't get the result we want, we will have to work out how to
achieve that.

Well, a few conffiles remain: /etc/init.d/cyrus2[12],
/etc/default/cyrus2[12] at the very least AFAICT.

see above, at least two conffiles remain.

Yes, I did - because I thought they had no files left on the system,
which was partly true (for all but the -common package). That only
removed the conffiles it should remove (i.e. it left /etc/imapd.conf and
/etc/cyrus.conf on the system), but it also removed the statoverrides,
which we probably don't want.
