The thing is that systemd solves a lot of problems for distros in a good enough way (frankly, currently in a way that is better than any existing alternative) that they are happy to have systemd deal with those issues while they focus on the stuff the distro makers are interested in.
Systemd favors the distro maintainer and cloud application service provider, and maybe the appliance manufacturer.
It's the exact opposite of a useful tool empowering the the individual.
Not a given, since one of the issues with systemd is its integrations. Replacing init now requires you to replace your system logging and session manager, at a minimum, as well as replace all your service files.
Unlike e.g. upstart in its native mode, systemd can run SysV init scripts.
