I don't think we're too far off from at least making cgroup1 a CONFIG
option. As for the /proc/cgroups file, it's mostly useless on cgroup2, so I
was hoping that this could be put behind the same CONFIG option. I haven't
really thought through it tho, so it's not a hard set plan or anything.

Thanks.
