This would work, of course. Your example is not complete, it assumes
that there is already a detached session running on socket
/tmp/detach.session. I suppose it is a shell, because you're sending
shell commands.

This approach isn't sufficient I guess. You can send any shell command
or program to be the remote shell, but these commands cannot read any
thing.

Furthermore, Tramp would need to perform a kind of bookkeeping, which
detached sessions are available on the remote host. I doubt users will
accept midterm, that only one detached session, with a hard coded socket
path, are available on a given remote host.
