Not really: quite a lot of GUI-related settings can be done before the
GUI setup is done.

That'd be risking problems that can be avoided.  If we document that
file as being loaded only by batch sessions, we won't need to solve
bugs where people loaded it in interactive sessions and that didn't do
what they expected.
