ChromeOS doesn't use systemd, either. (It uses upstart, which I am guessing they have to maintain without any significant outside help.)

I'm pretty sure ChromeOS is getting upstart from their Gentoo base, so what little maintenance it needs should be shared. And I do mean little maintenance; without systemd's infinite scope creep, an init system could reach "done" and coast indefinitely.
