> WebRTC data channels support peer-to-peer communications, but WebTransport only supports client-server connection. If you have multiple clients that need to talk directly to each other, then WebTransport isn't a viable alternative.

That's disappointing. I have a peer-to-peer application where I'd like to be able to use QUIC streams rather than the current SCTP-based WebRTC data channels. In particular, it seems to me that QUIC streams would be better for transferring files peer-to-peer in a way that takes full advantage of available bandwidth without causing congestion or doing excess buffering on the sending end.
