HTTP/3 is everywhere but nowhere

    > At the same time, neither QUIC nor HTTP/3 are included in the standard libraries of any major languages including Node.js, Go, Rust, Python or Ruby.

.NET actually looking like it has decent support for any teams that are interested[0]

Support for Windows, Linux[1], and Mac[2] (the latter two with some caveats).

Overall, I think for most dev teams that are not building networking focused products/platforms, HTTP/3 is probably way down the stack of optimizations and things that they want to think about, especially if the libraries available have edge cases and are too early for production. Who wants to debug issues with low-level protocol implementations when there are features to ship, releases to stabilize, and defects to fix?

How much does http/3 help for server to server traffic? Seems like larger websites can use a CDN or load balancer to do termination and then use http 1.1 to the back end. Is that good enough with large pipes and a high number of connections?

My recent projects in C++ are just using cURL, but given some of the versions of cURL I have to support are 10 years old it isn't being turned on anytime soon.

Even the latest deployments on Rocky 9 are using a 4 year old version of cURL

When you're writing libraries distributed as binaries for other teams you can't just statically link whatever you want willy nilly.

What prevents you from using a package manager linking statically with a recent libcurl ?

For bidirectional 2 TCP sockets and HTTP/1.1 Comet-Stream works fine.

Fighting HTTP/1.1 for money is going to fail unless you invent something fundamentally better.

as an indie web master, some percentage improvement on ttfb brings zero benefit to me and my users, but requiring or recommending it to users only help big tech.
