We use systemd all the time to restart services and query for their status, but it can do a lot more than just that.
It can be used to analyse the boot time of the system (systemd-analyze), to display realtime information of the processes in a top like manner (systemd-cgtop), display the status of the whole system in a tree like manner (sudo systemctl status) and many more.
Of course none of these is new, you can do this in a number of different ways, but it seems systemd is replicating a number of other tools.
