So dlc is a fork of dl, but dl itself has actually a bunch of fairly recent commits which dlc does not have. And dlp nor dlc are 'forks' in the Github sense of forking. So how does one figure out whether recent dl commits are in dlp? And does this matter? Is this the downside of 'if you don't like it then just fork it and fix it'?
Other than a few commits [1], everything in youtube-dl is already in yt-dlp. You can see upto which upstream commit is merged into yt-dlp in the changelog [2]
