You don't understand. "Supercharging" means hardware. It takes additional charging hardware to be compatible with a supercharger. On the Model S supercharging hardware was an option. I hope you are right but at this point it's still unconfirmed.
Thanks for that link. To me, 'supercharging' is the act of charging. And he specifically said supercharging, not supercharger hardware. So that is where the confusion came from.
