It may have been possible that USB Type-C specifications have not been updated, so the engineer might have decided to provide his own stance on things. With the specification improved overtime, we will definitely see more and more devices support both Qualcomm Quick Charge 3.0 as well as the Type-C USB interface, which has a ton of perks. Google+
