I don’t think they’re super valid concerns though - QUIC isn’t just dumb UDP that transmits as fast as it can, it has congestion control, pacing etc. built in

I don’t think they’re super valid concerns though - QUIC isn’t just dumb UDP that transmits as fast as it can, it has congestion control, pacing etc. built in that’s pretty similar to certain TCP algorithms, just it’s happening at the application layer instead of the kernel/socket layer handling it. In the design of these algorithms, fairness is a pretty key design criteria. If anything, potentially QUIC lets people try better congestion control algorithms without having to rebuild their kernels which could make the web better if anything…
