There appear to be a number of use-cases pulling on versions streams with slightly different requirements. That made me uncomfortable and I am concerned about the time taken to churn on such a public API, so rather that trying to get the API right at this point i felt it more expedient to focus on internal implementations, and when those implementations settle we can stand back and see how to expose as a public API.
