Displaying variant products on parent page need improving

Looking at the current sandbox of Oscar and creating a parent product doesn't display any information about its variants. It is also a little misleading that it shows the "Add to Basket" button and quantity field without actually knowing which variant is select.

What should the the product page for a parent product look like? How should the basket be handled? Was the drop-down removed on purpose or accidentally?
