HTTP/3 and Crystal frameworks

I was reading up on the new HTTP/3 standard and was wondering how ready are the Crystal web frameworks are for implementing/using it.

AFAIK all web frameworks build on top of HTTP::Server and that’s not ready for HTTP/3 at all. It doesn’t even support HTTP/2 (see #2125).


The wikipedia page lists implementations in C, C++, Go, Java, Python, and Rust, so at least Crystal devs/implementers don’t have to start from scratch, and also have ref implementations to test against.
