Configured in this way, this connector looks for an ALPN protocol, and
if none if detected, it falls back to a default protocol, typically
http/1.1.

Okay.

Do I understand correctly that you want the client to connect to the
server *knowing* that on that port the server will speak HTTP/2 ?
You don't want to do any protocol negotiation, you just want to hit
the server with h2 (i.e. TLS+HTTP/2), no fallbacks, no other protocols
spoken by the server. Correct ?
