Without HTTP/1.1 either the modern web would not have happened, or we would have 100% IPv6 adapation by now. The Host header was such a small but extremely impactful change. I believe that without HTTP/3, nothing much would change for the majority of users.

But also, the only thing in most of the organizations I've been in that was using anything other than HTTP 1.1 was the internet facing loadbalancer or cloudflare, and even then not always. Oh yeah we might get a tiny boost from using HTTP/2 or whatever, but it isn't even remotely near top of mind and won't make a meaningful impact to anyone. HTTP/1.1 is fine and if your software only used that for the next 30 years, you'd probably be fine. And that was the point of the original comment, nginx is software that could be in the "done with minor maintenance" category because it really doesn't need to change to continue being very useful.

Maybe you just haven't been in organizations that consider head-of-line blocking a problem? Just because you personally haven't encountered it, doesn't mean that there aren't tons of use cases out there that require HTTP/3.

I have not. It is quite the niche problem. Mostly because web performance is so bad across the board that saving a few milliseconds just isn't meaningful when your page load takes more than a second and mostly is stuck in javascript anyway. Plus everybody just uses cloudflare and having that CDN layer use whatever modern tech is best is very much good enough.

Sure, but there's video streaming, server to server long polling bidirectional channels, IOT sensors and all sorts of other things you probably use every day that can really benefit from HTTP3/quic.
