is the sourcecode of systemd the *only* example implementation of an
INIT 1 daemon using cgroups right now?

here I see a lot of Go code
https://github.com/search?utf8=%E2%9C%93&q=cgroups&type=

so why systemd is considered to be the only supervisor implementation
supporting cgroups? because all the rest are just libraries?

I'm a bit confused and very curious
