It could be really handy, sometimes I click a video post by mistake (easy to do by mistake, I liked colored triangles in the thumbnail corner like relay did on Reddit) and (with current YouTube) can’t exit it fast enough, sound goes blasting when I don’t want it to (because back gesture won’t exit the video but minimize it to show me the rest of YouTube’s glory)
If you use NewPipe, you can turn off autoplay in it’s settings so that if you accidentally click on a YouTube link, it’ll launch the video in NewPipe but won’t start playing it automatically.
