If `CURLOPT_HTTP_VERSION` is set to `CURL_HTTP_VERSION_2_0`, libcurl will use
ALPN (or NPN) to negotiate which protocol to continue with. Possibly introduce
an option that will cause libcurl to fail if not possible to use HTTP/2.
-Consider options to explicitly disable ALPN and/or NPN.
ALPN is the TLS extension that HTTP/2 is expected to use. The NPN extension is
for a similar purpose, was made prior to ALPN and is used for SPDY so early
HTTP/2 servers are implemented using NPN before ALPN support is widespread.
+`CURLOPT_SSL_ENABLE_ALPN` and `CURLOPT_SSL_ENABLE_NPN` are offered to allow
+applications to explicitly disable ALPN or NPN.
