From user side Youtube discovery is almost completely broken anyway. I ended up removing both home feed and recommended videos block via extension because they didn't contribute anything besides frustration and page load time for a couple years now.

I learn about creators elsewhere and then look up and subscribe to their channel on YT. This flow will work just fine with p2p as long as creators have a video list and an rss feed anywhere on the internet and a single functioning search engine continues to exist.
