Not necessarily.

I routinely run other commands in a daemonlike mode, without the command itself having "make myself a daemon" functionality. If I were writing the launcher in Python (and my "setsid" script is Python already), I would be doing all the daemon bits in Python including the fork, then execing the other tool.
