So I've read. What I have not been able to find, is information on what 
subset of the ssh_config(5) options libssh (and, in particular, the 
libssh version built into the x2go mac client) recognizes. Do you know 
more?

I've read about that. Problem is: I need to come up with a workable 
solution for three dozen users, many of whom are not ssh savvy, on 
three different platforms. And tweaking configuration outside of x2go 
just to connect to a different host is not practical for them, even if 
I can make it work for me.

I might, if I could find said debug switches, which is what my question 
was about... Please fill me in.

The jumphost allows port forwarding only, no sessions there.

Since the x2go client does offer support for an ssh proxy connection: 
How functional is it? And what is the intended setup, i.e. what is 
expected of the proxy?

Cheerio,
