My reference to 7540 8.1.2.3 explicitly talks about non http schemes (ftp is the most common). That doesn't make CONNECT/TUNNEL non http.. it just means http is being used to interact with a non-http service..

FWIW, we do change the scheme from the API perspective:
https://fetch.spec.whatwg.org/#websocket-protocol (details in section
6.2). The reason for that is 1) the handshake is a simple HTTP request
2) it makes it a lot easier to share HSTS, CSP, Mixed Content logic,
etc. So by the time it gets to the protocol there's no ws/wss. I think
ws/wss was largely a legacy thing from when we still thought it
wouldn't require HTTP at all.
