The aggregation of these services are all understandable, because every one of them is about running a service. They might be triggered by different events (timer, network connection, at boot, manually), but other than that they are all doing pretty much the same thing: setting up and running a service.

It isn't building in an NTP client, or a hostname resolver, or configuring your network, or taking over the system logging, or generating QR codes. It has a singular focus and design which makes conceptual sense. It's not a dumping ground for a disparate collection of poor quality alternatives to existing tools.
