I don't think the guy who you replied to expects anyone to implement their own SSH client to build a tunneling feature. The sensible thing you would do is use a well known library for that.. but that's not any less work than having your program use the SSH binaries to make those features. Honestly it would almost certainly be easier to use a library.

Even easier to just have a doc give some examples of third party tunneling solutions and not have the app try to do anything more than normal connections.

ssh tunneling alone can be done in so many ways with different environments necessitating which might work. are we talking ssh tun/tap IP tunnels? simple port forwarding? either of the above but with a proxyjump required to get there?
