I do recall reading about some people who put the blue bags on their fruit (I think it is common practices amongst commercial banana plantations) but I cannot recall the point. Maybe you are correct that it is to speed maturing, but likely not ripening, as they are picked green and shipped out. It may also be to protect the fruit from damage from insects and the leaves hitting them. I never put plastic bags on mine and they do just fine.
