WebRTC (with p2p) was done within the W3C, as was a p2p QuicTransport. And this new API is similar to the open screen APIs that have been done in the W3C.
So I'm pretty sure work like this can be done in the W3C.
Try making webrtc work without a domain name and ssl cert. It shipped compromised so it couldn't be used without giving the server the potential to mitm all connections. its not p2p in any sense except network efficiency.
