Downgrading does not work well, so maybe instead of adding workarounds
for some of the problems, we should add a version check in .newsrc.eld
explaining that the user is on their own?

One thing that will break after downgrade + upgrade are flags.  Any
flag changes made using the old gnus version will be lost.  Given the
changes to agent/cache/etc, I think there are more problems.

Hm.
