I noticed that tokio-quiche already has HTTP/3 DATAGRAM flow support and some CONNECT-UDP-related plumbing.

Is there interest in extending this further toward upstream RFC 9298 / RFC 9484-compliant CONNECT-UDP / CONNECT-IP support in quiche, for example by starting with incremental Capsule Protocol groundwork first?

I’ve been experimenting with this direction in my fork, so I wanted to check whether this would be a welcome upstream direction before opening PRs.
