There's nothing stopping QUIC from being p2p. In fact, the original version of WebTransport was called QuicTransport and was p2p, but there was more interest in client/server use cases, so we switched focus to that. (I'm one of the original authors of the WebTransort spec and when I worked at Google years ago, some excellent engineers on my team shipped the original QuicTransport behind a field trial).
