ALPN carries all the important and relevant version information, yes. Version information is all carried in the identifier string (currently "HTTP/2.0"). This same identifier is used in ALPN and Upgrade (and Alt-Svc and DNS and whatever other places we choose to signal support of HTTP/2.0). Note that this is all outside of the protocol, and is always required to be present, though we acknowledge that the presence of the identifier might be implicit (as it would be in the port 100 proposal).
