That ended up requiring the ability to charge from a micro-B cable, even if it needed an adapter to the lightning, USB-C, or other proprietary port on the phone. Probably a good thing too, or else USB-C would have been dead in the water for phones. It's not clear to me whether they simply want to update the regulation from micro-B to USB-C (which would require development of a lightning to female USB-C adapter, but would probably reduce the number of phones that still have micro-b ports), or whether they want to really mandate the port side this time.
