It really does, but it also already has it via RFC7838 (HTTP Alternative Services / ALTSVC), which is normative for HTTP/3¹, albeit an optional client behaviour. Unfortunately not via DNS; you still have to run the origin on a well-known port if not specified in the URI. Clients supporting ALTSVC are then defined to use them at a requirement level of "should"².
