There is a reason for USB-C extensions not to be part of the standard. They can be bothersome in the best case and dangerous in the worst.

I am highly sceptical of anything that would connect USB voltage, no matter how finely negotiated, directly to the battery terminals. Finely tunable voltage over USB is useful for keeping the buck/boost converter on the device side small, though, or just efficient because it doesn’t have to do as much work. If you can charge over standard PD extending to charging over PPS should only be a software change as your hardware is already more than capable.
