You might wish to try an approach where people who do think such a thing
might be useful can voice their support for it rather than trying to
convince people who don't presently see any immediate use cases that there
are some (without saying what those use cases are...).

In short - post to -general.

As you note - moving runtime checks to "SET" time has value and this patch
brings that value. But it is not evident there is enough value to take on
the added complexity. There are few to no requests asking for this ability.
