One of the benefits of the engineering products is the additional functionality for number nomenclature, adding attribute value on the creation process, and release policies. Unfortunately you can't create engineering products that are setup to use constraint based configurations. When companies have a mix of products with different configuration technologies, it is challenging to have different methods for creating and managing those products. Even if the BOMs can't be engineering controlled, it would be very beneficial to have the products themselves setup as an engineering product with all of those additional features.
