But as the article points out HTTP/3 is designed to be reliable. This is why TCP is not really great for realtime/low latency video. Re-transmission of old frames is the opposite what you want for live streaming. If you can't re-generate the frame from forward error correction, then you're shit out of luck. if you're hitting network throughput limits, wasting data on transmitting frames you cant display is not a good use of a limited resource.
