This isn't systemd dictating cgroups2 or systemd trying to get rid of 
v1.  But systemd is a common user of cgroups, and we do use it here in

We're just sending patches upstream for the tools we're using.  It's 
better than keeping them private, or reinventing a completely different 
tool that does almost the same thing.
