With the goal of getting it into GNU ELPA? I'm not sure. I think there are nine people in the git commit logs, so it's probably doable, but a large part of its functionality depends on mpv, which is in NonGNU ELPA. Is it okay for ELPA packages to depend on NonGNU ELPA? The ELPA readme doesn't have the same kind of section on dependency restriction that NonGNU ELPA's readme does, and a quick search of emacs-devel for gnu elpa depend nongnu didn't seem to turn up an answer.

Also, the original author has mentioned not wanting to scare off contributors with the need for papers ( https://github.com/sachac/subed/issues/29 ), so I kinda want to stick with their wishes especially while I'm getting the hang of things.

It's probably going to be just fine in NonGNU ELPA, right? It's pretty niche, but having it in NonGNU ELPA already helps a great deal in making it more accessible to less-technical users.

If it's easier for more people to work with captions and subtitles, maybe we'll have more accessible Emacs videos, and maybe even more non-technical users coming in to subtitle stuff. Let's see!
