Ugh :-(
I think that putting this into SET is a pretty bad idea in any case.
SET is, and always has been, a session-local operation. Providing a
secondary option that transforms it into something completely different
doesn't seem to me to be good design. If we do anything along this line
it should be some other syntax --- and really a specialized function
will serve the purpose just fine.
The other stuff you suggest is even more lily-gilding, not to mention
completely pointless unless we were to make this function the *only* way
that the settings could be changed.
