I don't get it either. Systemd units are so much more powerful and flexible than init scripts. Writing those bash scripts for everything was a complete pain in the ass.
You may disagree with the architecture or design decisions made with systemd, but I don't see how it's possible to argue that SysVinit was in any way actually "better".
