I am not really sure what you consider young but this interface is 4.0+
IIRC and the cgroup v2 is considered stable since 4.5 unless I
missrememeber and that is not a short time period in my book. Changing
interfaces now represents a non-trivial risk and so far I haven't heard
any actual usecase where the current semantic is actually wrong.
Inconsistency on its own is not a sufficient justification IMO.
