I think what they mean is that yes, the signalling needs to be done over "traditional" web APIs (websockets, etc), but that's just for discovering/negotiating the p2p connections. The actual data transfer between the peers then happens over UDP which can have a bunch of advantages over TCP for some scenarios.
It's actually quite easy if you can find a networking library: bind and listen on a socket on port 80, read text until you get GET / HTTP/1.1, discard whatever comes after, write back a response containing "Hello World" in the correct format (few lines of text) and that's it! A new full stack web app is born.
the value the js community gets from `fetch` being a unified standard is far, far greater than the benefit you as a developer would get from not having to add 15 extra LOC around `fetch`, that you'll probably hide behind a `fetchJSON` function anyway.
You're going awfully out of your way to not engage with the arguments you're presented with by other people, dismissing them with sardonic one-liners, and making wild assumptions about the motives and thought processes of the Apple employees. If you're not trolling, I suggest you take a couple steps back and reassess the situation, because you're not coming across as a reasonable person.
