Issue
Currently there is no simple way to check what quote item was just added to the cart. This causes issues for module developers who need to work out what item was added to the cart for a custom module.
Possible Solution
Right now we have:
$this->checkoutSession->getLastAddedProductId();
To get the last added product however there is no way to fetch the item id. A possible solution is to give us a saved session for getLastAddedItemId for example:
$this->checkoutSession->getLastAddedItemId();
