QUIC has support for unreliable data via the DATAGRAM frame, RFC 9221 <https://www.rfc-editor.org/info/rfc9221>. It seems that this new proposal attempts to add unreliable data support not to QUIC, but to QUIC *streams*. QUIC streams, of course, offer a reliable, in-order, sequence of bytes. Did you consider starting with DATAGRAMs, and building from there instead?
