Systemd didn't create this problem. But it solves the issue of distributions shipping config files as part of packages and then on every package upgrade having to reconcile between the distribution's config and your modifications. Now with the drop in system you don't need to do that.

I am not an expert but I think in general systemd has a lot of complexity but it's to handle existing issues in a better way. Some of the older init systems might be simpler to describe or get started but lead to more confusing situations in the long run.
