I think I agree with this change. The only thing the old version could do
is run generic recovery code, and if there's generic recovery code, it can
just go into the new version directly where no fallback is required.
Downgrade is basically unspecified in Policy right now. It would be
interesting to do the work to specify how things behave, although I
suspect it would be a non-trivial amount of work.
