Fair enough. Even if it's not super-common, it doesn't seem like a
great idea to regress such scenarios in the back-branches.

Is there any way that we could instead tweak things so that we adjust
the visibility test object itself? Like can have a GlobalVisTest API
where we can supply the OldestXmin from the VacuumCutoffs and have it
... do something useful with that?
