Sure, but there is no male-lightning to female-lighting cable so users would NEED to bring a cable and brick with them everywhere. The Pencil1 was designed long before compatibility with a USB-C iPad was a consideration. Their solution allowed people to just bring the iPad and Pencil.
I don’t know what you’re saying. The pencil
is a pointing device just like the mouse. Both should have female ports to accommodate existing cables, not matter what they connect to on the other end. Just like the Apple TV remote, keyboards, trackpads, iPods, iPhones, iPads, AirPods, etc.
