The 'ssh' -N option is very useful here.

  man ssh

     -N      Do not execute a remote command.  This is useful for just for‐
             warding ports (protocol version 2 only).

That already sounds like a very custom configuration.  Is it really
worth a pause command in coreutils for this very specific case?  It
would seem much easier to set up a custom shell as I am sure you have
already done in this case.
