I don't understand why server push is in the standard but not Early Hints. I saw some articles but seems both server side & client side support are lacking. (

  103 Early Hints is RFC 8297. It defines a status code. Because status codes are an HTTP semantic, they are common across all HTTP/1.1, HTTP/2, and HTTP/3. There's nothing special that needs to be done from a specification perspective, early hints _can_ work on any version. Whether implementations support that is a slightly different matter.

  FYI early hints support is coming to Go, so it's possible that Caddy will gain support for it in a while (it'll need Caddy to have Go 1.19 as minimum so it's still like about a year or so away probably)
