Overall fairly minor changes, but most importantly the Host header passed to the backend is set to $host instead of $http_host as HTTP/3 no longer uses the Host header, leaving it unset. $host will fallback to the server_name value in that situation while $http_host doesn't.

Does this work without http3 on (and potentially some more quic settings) in the server block (or globally)?
Or is this enabled by default in new-enough nginx?

http3 on is the default when using the module: https://nginx.org/en/docs/http/ngx_http_v3_module.html
