QUIC is now officially HTTP/3, as described in RFC 9114 <https://www.theregister.com/2022/06/07/http3_rfc_9114_published/>. Not everybody is keen on it: there still seem to be some concerns over privacy, as well as over the claimed performance boost. Actually, a previous spec (RFC9000) had “Proposed Standard” status over a year ago, but it wasn’t (officially) being referred to as “HTTP/3” back then.
