This is not correct for devices being sold to the EU at least. Part of the amendment to the Radio Equipment Regulation outlines the exact standards for power delivery that must be used, and that interfaces which are capable of being charged @ > 15W must "ensure that any additional charging protocol allows for the full functionality of the USB Power Delivery...".
For data transfer, I don't see the point and future improvements to USB will come from industry in future.
The only way around this is with a wireless charging protocol, but manufacturers are moving away from that it appears.
