Can’t the cable terminate it instead? That would save a lot of wire, and consumer expectations for USB-C reliability are just above “might catch fire” and below “I’d be surprised if the cable was incompatible or failed so quickly”.
You'd end up with a cable that only worked for "slow charging" (5V / 500 mA), and even then only in one direction (because the cable could only pretend to be Rp+Ra or Ra+Rd for one side). It's easier to do the right thing.
