And then you have the standards for not just raw data speed, but also what other modes are supported, for information to be seamlessly tunneled through the cable and connection in a mode that carries signals other than the data signal spec for USB.

Not to mention power-only cables to avoid the security issues associated with cables that permit data transfer.

"Power-only" meaning no data BEYOND the PD devices themselves because its actually a data protocol to negotiate the power output to the device.
