If the complaint is "I can do X before 9.6.0 and after 9.6.0, but not in
9.6.0", it doesn't really matter whether it would take a catversion bump
to resolve; the problem is lack of a time machine. Once there's a
released 9.6.0 out there that is missing something important, applications
that care about version portability are going to have to deal with it.
So we need to get this right the first time.
