What's funnier is that Apple already has an iOS device that has USB-C for its main port, the iPad Pro. So I'd presume most of the engineering work to get rid of Lightning completely has already been done at this point. On Switch, I did charge mine from a powerbank with a USB-A to USB-C cable, it did work but there clearly wasn't enough power. The battery kept draining but very slowly.
