Note that HTTP has this issue (HTTP 1.1? 1.2? Soon 1.3 which does not
even use TCP?) It is "solved" by some mixture of signaling in the DNS
<https://datatracker.ietf.org/doc/draft-ietf-dnsop-svcb-https/>,
redirection when possible (Alt-Svc:) and intelligent guessing, probing
and memorization by the client.
