On the contrary; with Type=simple systemd has better control on the
service, since systemd itself execv() the service binary, and it can
know precisely its PID and when it finishes. With Type=forking systemd
has to guess what the PID is, and therefore it nees more work to know
the status of the service. It does a pretty good job, but it's easier
with Type=simple.

Type=forking is there for old daemons that don't have a --foreground
or similar option.
