Sorry but this argument really falls flat. All of the other init systems' service files are reminiscent of SysV say OpenRC or runit.

Moreover systemd achieves what it does because it provides a unified way of doing system administration. It is not only a service manager. It is the much needed dynamic system layer for Linux.

A modern Linux engineer or a sysadmin, no longer needs to make 5 to 10 different services work together by duct taping everything or writing abstraction layers per integration. Any system that has the correct level of abstraction will be at least as complex as systemd.
