We could stop the sync of a folder having any filename with a unexpected
MD5 in order to prevent from doing bad things.

The CLI option has the benefit we can backport the feature. Some users
will want to downgrade offlineimap for whatever reason. They will have
the same issue in the other way around.

I guess we will have complaints. Also, I'm not sure what we do when MD5
does not match. I worry about email deletions on remote if the filenames
are fully ignored by the merge algo.
