[arch-general] syslog-ng depends on systemd?

Hi, with the recent update of syslog-ng (3.3.6-2), systemd has been added as a dependency. I though systemd providing its own logging and syslog-ng wasn't needed. Then why is systemd needed for syslog-ng to run? As far i can see from the diffs, nothing has changed apart from adding systemd as a dependency.
