Is fsh useful?

[Kai Gro�johann]

Some time ago, we discussed about fsh which I recall to be a way to
make remote commands using ssh faster.  The idea is that fsh opens a
connection to the remote host once, then subsequent invocations reuse
the existing connection for new commands.

I think that fsh is not useful anymore, given the way Tramp operates.
But maybe the scp or rsync using methods could be made faster with it?
(Though I have no idea how that could work.)
