PoE has been around for longer, and while it doesn't go that high (90W --- but at much longer distances), it uses passive cables just fine.

POE is an quite expensive thing to implement on a board. Flyback transformers are essentially required to support the standard.

At the cost of much higher complexity on each end. USB-C still supports completely passive old chargers and devices.
