YouTube still does

    <feed xmlns:yt="http://www.youtube.com/xml/schemas/2015" xmlns:media="http://search.yahoo.com/mrss/" xmlns="http://www.w3.org/2005/Atom">

I don't think they are linked to anywhere but the url is http://www.youtube.com/feeds/videos.xml?channel_id=<channel_id>

GitHub too for their releases; you just add /atom to get the feed, which works great.

GitHub have some quite nice feeds

If you want all the commits from a repo you can do something like: https://github.com/rust-lang/rust/commits/main/.atom

And if you now only is interested in the num module you can do: https://github.com/rust-lang/rust/commits/main/library/std/s...

The channel pages still have auto-discovery links. So if you paste a channel URL into your feed reader it should find the feed easily.
