Yes, it's intentional.  RFC7540 allows coalescing based on the cert and DNS, because you're connected to the authoritative origin.  However, HTTP/3 is never connected on the authoritative endpoint for an http(s?):// URL, so you need something else to tell you that's okay.  This could be an Alt-Svc record for that origin delegating to the same UDP port.  This could be an ORIGIN-for-H3 frame telling you to throw caution to the wind and trust the cert, if the client thinks that's sensible.
