It's not like we already had a cable and protocol that could encapsulate arbitrary data and transmit it between devices without concern for what upper level protocols were in use or what the data type was, with the only concern with regards to the cable being the max speed supported. Oh, wait, Ethernet is a thing. I wonder how they just completely missed that when making USB 3. The only thing that should be differentiated between cables is max power delivery rating and data rate.
