In hindsight, I tend to agree with your conclusion.

But since the default is recursive deletion, implementors can choose
to add an option controling the behavior (and perhaps we could even
standardize such an option). But it is in my view not OK to simply
implement a different behavior since clients may rightfully expect
recursive deletion as this is what the specs says.
