Corporate firewalls will be blocking QUIC until the end of time. Anyone implementing streaming over QUIC will have to have to implement an HTTP/2 fallback, probably WebRTC, but maybe we will get something new.
In the case of QUIC, it is likely that the streaming would be over H/3 (HTTP3) or HTTP over QUIC. They may fallback to H1 or H2 but typically over a long enough time, firewall rules become more relaxed.
