Right. Getting rid of custom_variable_classes should actually make
those use-cases easier, since it will eliminate a required setup step.

I tried to think of a security argument for keeping the setting, but
couldn't really. Yeah, not having it will let people clutter their
individual backend's GUC array with lots of useless stuff, but so what?
There's plenty of other ways to run your session out of memory if you're
so inclined.
