For 15.04 we plan to change to systemd by default, at which point this will work. For 14.10 making systemctl "invisible" is not an important enough issue to warrant a stable release update; plus, some people actually want to boot 14.10 with systemd for experimentation (note that this is not officially supported, and some things are known not to work).
