True, you do not have to have the service running in foreground mode.
But it would make systemd happier.

You're starting it in forking mode. systemd would be happier, if you let
it run in foreground, but that's not a must. I believe, using
Type=forking in your case would be advised.

And perhaps using PIDFile=${PIDFILE} (not sure if ${…} works here)
or GuessMainPID does a good job already and you can simply
ExecReload=kill -s HUP ${MAINPID}
Here is mine:
# /lib/systemd/system/exim4-daemon-exim.org.service
[Unit]
Description=Exim MTA
[Service]
EnvironmentFile=/etc/default/exim4-daemon-exim.org
ExecStart=/usr/sbin/exim -bdf ${DAEMON_OPTS}
ExecReload=/bin/kill -HUP ${MAINPID}
#this made problems on a system
#ProtectSystem=full
#ReadWriteDirectories=/var/spool/exim4
#ReadWriteDirectories=/var/log/exim4
[Install]
WantedBy=multi-user.target
Alias=exim4.service
