The reason most DC power delivery systems failed to be general purpose was that unless you pick some not very useful lowest common denominator voltage you need some sort of data bus to request/negotiate/handshake voltage for each device. If you are already building in a data bus into your power delivery lines you might as well give it some speed so that you could run other communications over it, at which point you likely just wind-up reinventing something like USB if you are planning a "simple, dumb DC power delivery standard".
