USB 2.0 specifies a maximum of 20AWG wire width for power transmission, which would limit you to 1.5A for charging.

We're talking about usb-2.0 data over usb-c cable. It'll still have the power delivery of usb-c

And that wastes physical real estate that could be used for a more modern cable. And with more USBC / thunderbolt cables around, theyll also get cheaper.
