Woocommerce

Hi, i was just about to create some packages on my site to make some test purchases. I was very surprised that GD has nothing to do with woocommerce. My question is, why? There’s so much good that comes with woocommerce, for example the checkout, the gateways, the products with images, product descriptions, SEO (products that are indexed by google), a buy button, products that can be shown on frontpage, to be able to add 2, 3 or why not 10 packages to cart and go to checkout.. etc… Why not implement GD with it like WP Job Manager has done? I don’t understand, it doesn’t make sense.
