I guess its there to improve access to cool air flow? However the word "cool" has to be taken in the context of ambient temperature. If you lived near the North Pole you would probably be looking to block up every orifice to keep the heat in. Well, to a certain extent. At the equator the opposite. So its difficult to say really.
