In a systemd world apps should be pretty wary of using libcgroup to make changes. Systemd expects apps to honour the "single writer" view of the cgroups hierarchy, and thus only considers it valid for apps to make changes if they've requested that systemd delegate a particular sub-tree to them[1]. This was already true in v1, but iiuc there's better enforcement around delegation in v2.
