I see this pattern in more Microsoft products. 1. Publish a default implementation with plugin support 2. Popularize and sell product 3. Add a small subset of popular plugin features to next version. Ensure to never implement the full set. 4. Release improved version of product 5. Plugin will enhance with newer features 6. Repeat steps 3-5 If done right, this will work for both product and plugin implementors.
