I think we'll see some DNS version of alt-svc that doesn't require TCP to bootstrap.. see httpssvc and svcb
There won't be a pure HTTP/3 service anyway. HTTP/3 requires negotiation. It is announced from a previous HTTP/1.1 or /2 request using a "Alt-Svc" header. Typical clients will not try to connect using HTTP/3 directly
