Would be interested in this too, I did some work in the past to make it work via Envoy proxy using HTTP CONNECT but that requires plugging in proxytunnel[0] or nc on client side.

  > $ nslookup abc.exe.xyz  
  > abc.exe.xyz canonical name = s001.exe.xyz.  
  > $ telnet s001.exe.xyz 22  
  > Trying 100.20.12.135...  
  > Connected to s001.exe.xyz.  
  > Escape character is '^]'.  
  > SSH-2.0-SSHPiper

Looks like it uses sshpiper[1]?
