The rules were invented when Nitrox involved selling your soul to the dark side and without training you were obviously going to kill yourself at once and, well, who wants a haunted dive shop?
These days we know it is air that is madness to dive and teach nitrox before we teach mask clearing but the rules have yet to catch up. Air is an acceptable mix in the pool but optimum nowhere. It is just so convenient.
