Why is this an important feature for beancounters? All the other resource control approaches seem to prefer having userspace handle removing empty/dead groups/containers.

Why is depending on a feature like configfs worse than depending on a feature of being able to extend the system call interface?

That's fine - some people don't want total isolation. If we're looking for a solution that fits all the different requirements, then we need that flexibility. I agree that the default would probably want to be that the groupings be the same for all resource controllers / subsystems.
