I think we should avoid that -- if "depends" means "needs, in order to
be useful". Everything in core Emacs should work and be useful without
ELPA. And everything in GNU ELPA should work and be useful without
NonGNU ELPA.
As it turns out, subed-mpv.el doesn't even use mpv.el, as it implements its own process control for the external MPV video player, so no problem at all. :) Uh, yes, I did actually accept the maintenance of a package that I've only read about half of, but that's mainly because I kept submitting patches for the stuff I wanted to tweak and the original author hasn't written Emacs Lisp in a while... I will try to not make a mess of things while I'm squeezing coding/email into my sleep-deprived discretionary time. :)
The idea of NonGNU ELPA is to be add-ons to the rest.
It's probably pretty reasonable to keep subed in NonGNU ELPA instead of GNU ELPA, anyway.
