Precisely. We've said right along that we reserve the right to have a
non-upgradable disk format change whenever sufficiently many reasons
accumulate to do that. The way to go about that is to collect projects
that need to be kept on hold for such a release --- not to say we're
going to have such a release and then look for reasons.
