Interesting. Having HTTP/3 layered over the top, which I presume allows for SSL certificates to be applied to the connection, might result in the SSH connection appearing to observers as standard - uninteresting - website traffic. Assuming one could connect to an SSH server this way and tunnel ports, could this allow for a means to bypass China's GFW? China's firewall allows http and https connections through however VPNs, SSH and similar are detected upon connection and blocked on demand. Hiding a VPN connection by tunneling to a remote SSH server over HTTP/3, forwarding the VPN port and connecting to it might fly under the radar as it could be perceived as regular web traffic. Would be an interesting thing to try.
