Actually, the sane interface would likely just be to have a "drop on
release" interface.

Maybe some people really want to be _notified_. But my guess would
that that just dropping the cgroup when it becomes empty would be at
least a reasonable subset of users.

Who uses that thing now? The desktop launcher/systemd approach
definitely doesn't seem want the overhead of being notified and having
to remove it manually. Does anybody else really want it?

But that's really an independent question from all the other things.
But with new cgroup users, it's very possible that it turns out that
some of the original interfaces are just inconvenient and silly.
