I believe this is only talking about the piece that connects the charging cable to the electrical system. Apple already ships a charger that has a female USB-C on one side and male electrical plug on the other which will satisfy this proposal. You would then still use a USB-C to lightning cable to charge the phone but you could reuse the the charger itself between android and apple.
