I don't think much has changed to be honest.

An application that would have wanted to use multiple WebSocket flows and paired request/response flows using HTTP/1.1 would have just had to manage multiple connections one level up.

The HTTP/2 equivalent is a single layer that does two things, rather than two layers that do two things as we have with QUIC and HTTP/3.

The use cases and complexity exists no matter where we push it around to.
