CONFIG_CGROUP=y isn't a requirement for parallel boot. People have been doing that for years without it. And I'm not against systemd using cgroups per-se, I'm against it mandating it. It could simply not use them and not provide whatever it needs them for when not present. CONFIG_CGROUP is an option, so people can say no. Same for CONFIG_SYSFS, udev gets highly unhappy when disabled, but init still works and you do get a shell of some sort. If you pre-populate your /dev with static device nodes you can actually make it all the way to runlevel 3 the last time I tried.
