I am confused... >From a kernel PoV: - Prescriptive = here are the available hardware blocks, feel free to configure each as you like - Descriptive = give me the source and destination color-spaces and I take care of everything This proposal is a prescriptive API. We haven't explored _that_ much how a descriptive API would look like, probably it can include some way to do Night Light and similar features but not sure how high-level they'd look like. A descriptive API is inherently more restrictive than a prescriptive API.
