I have been very happy with the recent cases where I have used an interface for the API but provided a default implementation, with the admonishment that implementing the interface without extending the default implementation is likely to be broken in the future. That way the people that care more about being able to substitute alternate implementations or to use it without having to extend the implementation can implement the interface, and those that care more about not being broken by future updates can extend the default implementation. -- John A.
