问题
I would like to know if it's possible to make G-WAN 100% compatible with HTTP/2 by using for example the solution nghttp2 (https://nghttp2.org)

Sorry for the late answer - for any reason Stackoverflow did not notify us this question and I have found it only because a more recent one was notified.
I have not looked at this library so I can't tell for sure if it can be used without modifications, but it could certainly be used as the basis of an event-based G-WAN protocol handler.
But, from a security point of view, there are severe issues with HTTP-2, and this is why we have not implemented it in G-WAN: HTTPS-2 lets different servers use the same TCP connection - even if they weren't listed in the original TLS certificate.
That may be handy for legit applications, but that's a problem for security: DOH (DNS over HTTP-2) prevents users from blocking (or even detecting) unwanted hosts at the traditionally used DNS requests level (the "hosts" file in various operating systems).
In facts, this new HTTP standard is defeating the purpose of SSL certificates, and defeating domain-name monitoring and blacklisting.
Is it purely a theoretical threat?
Google ads have been used in the past to inject malware designed to attack both the client and server sides.
