Currently, we refactor product listings. The new implementation must support so-called "addon values".

Addon values are additional data that gets attached to the product. The data is stored in the addon_values_storage table and data associated with products is determined by the container_type_id column.

Additional data should be added to the ProductListingItem::$extensions, so they get serialized to an array.
This is very useful for third-party developers and our customizing team. This way, adding additional data to products that get passed to the theme is very easy.
