Commerce Line Item Views Handler for Remove From Cart functionality only works for product based line items

I created a custom line item (not based off the Product line item type) type for coupons the customer adds to their cart, which works great so far except for the fact that the Remove button in the views handler will not remove the coupon. I believe this is because the code uses a function which would only remove a product, which is reasonable, though I think coupons are a potential big exception to this. There is a "todo" comment in the code saying that in the future the dependency on the cart api for this functionality should be removed. Just mentioning it here in case this todo was forgotten and to ask if this item might be addressed in the near future. See commerce/modules/line_item/includes/views/handlers/commerce_line_item_handler_field_edit_delete.inc, line 63.
