I agree, but for the sake of completeness (and pedantry, I suppose) we should occasionally bear in mind (and occasionally say) that directivity matters only if choice, family or financial circumstances put you in a reflective room. I have been lucky enough to be able to build non-reflective rooms, where directivity is completely and totally irrelevant.
Some folks think reflections are essential per se, but no, you're better off without them. In my experience, listening in a non-environment is hugely, vastly, entrancingly, magnificently superior.
