I wonder if we can poison DEFINE_PROP_ARRAY somewhere such that it fails if DeviceClass user_creatable == true. That would let internal code carry on using it, while ensuring anyone creating a new user creatable device will quickly fnid out it doesn't allow these arrays. Rocker would need fixing of course.
