SSH does some kind of lower-level multiplexing. Multiplexing is unavoidable here because the local server must maintain simultaneous TCP connections that must be somehow distinguished between each other whereas the tunnel is just a stream of binary data.

I understand multiplexing is necessary. My point is SSH tunnels already multiplex. If two people connect to the same port on the tunnel machine then that will be two seperate sockets on the destination machine. Since they are already two separate sockets what is the point of adding HTTP/2 protocol awareness at the tunnel level? Just let the endpoints handle it.

Oh looks like we misunderstood each other. The fact is that h2tunnel is not using SSH, because my goal was a minimal Node.js native solution. So I had to look for a built-in alternative for multiplexing and found HTTP2.
