I’d go even further and say that HTTP/3 gives almost no gains for the average person using a high speed wired or wireless internet connection at a fixed location (or changing locations infrequently). However, for high latency mobile connections while roaming and continuously using the internet, it’s quite an optimisation. I wouldn’t expect even the vast majority of devs in FAANG to care. It should purely be an infrastructural change that has no impact on application semantics.
