This is incorrect. USB power delivery does not need the data lines. Negotiation happens over the CC line and Vbus line:

"A power-only receptacle Upstream-Facing-Port might only have VBus, GND, and CC pins populated, because they do not need the data transfer capabilities" source: https://acroname.com/blog/breakdown-all-power-delivery-types...
