Displaying Products directly by Views, not via Product-Display
having a very small site with a shop i wonder if there are any disadvantages when displaying products DIRECTLY with a view (i.e. NOT INDIRECTLY via a view which uses a node-reference to a product-display). Since none of my products need multiple product-nodes behind one product-display, it would be very handy to skip the generation of product-displays (or the deletion of them when deleting products).
products without product-display: is it a way to go or are there huge disadvantages?
