I just discovered sshs, and it looks like it could replace my previously cobbled together system, really neat!
But, I have a bunch of entries in my ~/.ssh/config that look like this:
Host prefix-*
HostName %h.example.edu
ProxyJump me@proxy-host
It would be amazing if sshs could understand the prefix-* syntax and match it when I type prefix-host1, or prefix-host2.
Also, parsing and understanding Match Host otherprefix-* would be nice too.
