I and quite a few others have Zazzle Stores that serve as a front-end to the Zazzle API. The products in the storefront are generally not visible to the public (because they are only templates), and are only created when the API is invoked from an external website.
The store usually only has a storefront description and together with the API created product descriptions these currently have html that direct the customer to the website for creating their products in these stores.
If all HTML is removed from storefronts and product descriptions doesn't this mean that it will not be possible for customers to follow a link to the external website to create their products using the API? Sounds like a backward step for managing API enabled stores
