Because systemd confuses a lot of things by having two projects with the same name.

Systemd the init service is excellent.

Systemd the catch all for trying to rewrite all services to come up with a baseline version of everything is a strange and NIH project. They would have been far better off politically by coming up with a spec and seeing if they could submit patches to get the current services to use the APIs they were planning.

Instead they just have a bundle of things they have tried to reinvent, some more successfully than others. Hence the divisions in the communities.
