hey Eugene, This is an exciting an useful addition! Have you looked into other platform APIs that could benefit from being able to explicitly specify intermediate format hinting and/or transformation? It's a place where (had the TAG been consulted) I would have expected to see a larger chain of additions to make this work in other areas, or at least a discussion of why they aren't (or are?) being pursued. Have you looked into that?
