For those that don't know, GrayJay allows consuming media from many platforms, all in one app. Peertube, Odysee (lbry), twitch, kick, removedute, nebula, soundcloud, and more!
You can also sync your playlists, watch list, subscriptions, and so on across devices.
I've discovered interesting creators across multiple platforms (peertube, odysee, billibi, dailymotion, ...) and have reached the point now where I can just switch of the youtube source and just consume media from all other sources. Billibi (Chinese youtube) for example has accounts that just sync/copy/rip entire channels from youtube and there are some creators that sync their channels onto peertube, odysee, or elsewhere. With Grayjay, it doesn't matter where anymore since it can probably access it.
What I enjoy a lot is not worrying about youtube updating and breaking the plugin because I just don't consume it anymore. You can give it a shot too.
I would encourage you to look a bit further. I typed "grayjay github" and right there are merged pull requests. There is also a CONTRIBUTION.md.
