Others working on systemd shims out of necessity is a sign, IMHO, that systemd is in reality a hard dependency in the near future (and developers trying to free from that dependency). I don't say systemd is not useful, GNOME using it shows also to good sides of it, but others feeling a little forced to choose systemd or The Unix Way I think is the wrong way to do it. Why can't we have both(modern init system and unix philosophy)? Not possible? Not enough interest/resources?
