Being entirely too lazy, I intended it to be run from a running Emacs
session. I was imagining it as sort of a "gnus -Q", as in "please submit
a repro starting with `gnus-mock'".

But realistically that's a dumb idea, and it should be made to be used
from "emacs -Q". That would completely obviate the need for all this
custom-variable tomfoolery. Maybe that stuff could be quietly added but
not encouraged.

The question remains, though: I think several of Gnus' defcustom's might
need :set-after clauses.
