What Daniel said. We're really only targetting HTTPS here, and HTTPS means TLS and ALPN when it comes to HTTP/2. Also, as a practical matter, HTTP/2 over TLS with ALPN is the only configuration that is widely deployed and available. curl is somewhat exceptional here in its promiscuity, but that's a core feature of curl.
