I'm fairly sure you can make about the same argument about
use_hierarchy. There is a choice to make here and one is simpler than
the other. I want the additional complexity justified by actual use
cases which isn't too much to ask for especially when the complexity
is something visible to userland.

So let's please stop arguing semantics. If this is definitely
necessary for some use cases, sure let's have it. If not, let's
consider it later. I'll stop responding on "inherent differences." I
don't think we'll get anywhere with that.

Michal, Johannes, Kamezawa, what are your thoughts?

Thanks.
