This question has been answered for Magento 1. (see: here). As I am migrating to Magento2 and need the same logic here is the issue:
I am trying to figure a way to hide show stock status/availability on the product page unless it is out of stock. I have all the settings configured to where it displays stock status on the front end as normal, however, I don't want to show "In Stock" only if the item is out of stock then I want it to display Availability "Out of Stock" only. A lot of our items are ordered through other vendors and drop-shipped to the customer therefore I don't want to display stock status on those items. Only the items we exclusively ship from our location.
