I think that position is sufficiently rebutted by Bruce's observation:

Since we are inventing this thing specifically to put it in dump files,
we had better take a very long-term view of its purposes.

That's why the code leaves it up to the individual validator routine how
much to check or not check depending on the flag setting. I have no
problem with an individual language deciding that it should or shouldn't
do a particular check. I do think that we'd be foolish to make advance
judgements about what those decisions will be.

Bottom line is that I wouldn't object to changing the switch name to
something more general ("restore_validation_mode", maybe?) but I think
that changing it to something more specific would be a mistake in the
long run.
