Improved networking eg IPv6 has been requested already.
Not sure what problem usb-c with PD would solve, would just add cost.
Reducing power draw to under 0.5a to allow more successful use of standard TV USB ports (which have limited piwer available) would be a benefit, would also reduce power supply cost and energy draw when plugged in with supply
