Yes, the "kill the newest memory cgroup as a tiebreak" is not strictly required in the kernel and no cgroup should depend on this implementation detail to avoid being killed if it shares the same memory.oom_priority as another cgroup. As you mention, it can be effectively implemented by userspace itself.
