@tapac I've opened #1123 and #1124 on GitHub. #1123 fixes a small issue in typing where you have to be more specific than the interfaces require. #1124 is a stab at fixing #1121, a performance issue where any insert or delete to a referring table evicts every tangentially related cache entry, which makes eager loading pretty much worthless. Let me know if you have questions or comments.
