Thanks for reporting! Given that the RFC status is "proposed standard" and that according to MDN it is only implemented by Firefox so far, I don't think that we should add it to the list yet, let alone treat it as bug. You can use header() to send that response code anyway.

This is (and has been for years) already heavily used by CDNs e.g. Cloudflare supports (and uses it) for origin pulls (since at least 2019 afair)

Since nginx https://nginx.org/en/docs/http/ngx_http_ssl_module.html#ssl_early_data supports it by default too, I think it should be handled in PHP.
