systemd is already used and from what I've seen there's far less complaints than PA[1], even talks of admins suggesting to look into it. That's for the 'not ready' part. For the rest, I'd agree with you, but I think the gain in abstraction and correctness is quite worth it, even with it lacks some simplicity.

[1] never encountered a single issue with systemd since archlinux pushed it as default, even on hybrid sysvinit scripts and naked systemd installs, compared to PA which may crash far too regularly, but that's just me.
