I remember trying that, and if I remember correctly, it broke with
core GUCs, without any need for extensions in the picture. I don't
remember the details too well, unfortunately, but I think it had to do
with the behavior of some of the check and/or assign hooks.
It's probably time to try it again, because (a) maybe things are
different now, or (b) maybe I did it wrong, and in any event (c) I
can't really remember why it didn't work and we probably want to know
that.
