The following dependencies are in the info file for this module: 

dependencies[] = commerce_line_item
dependencies[] = commerce_order
dependencies[] = commerce_product
dependencies[] = commerce_product_reference

My minisite uses only products, not orders (yet)
Since this module provides a widget/field/formatter, the dependencies on the first two modules seem too much, even though the module provides integration/hooks for these modules.

So, thes 2 modules could be removed from info-file or changed to 'recommended[]'.
