I'm a little dubious they can fit the Nano smarts inside the USB-C connector, like they did for USB-A. It's just so much smaller, and they didn't have a lot to work with before.
They can put it in a little nub outside of the connector like USB-A Wifi dongles [1] do. I don't care if it fits entirely in the USB port like the Nano, I just don't want it sticking out far enough that it'll get bent or damaged when I put my laptop in my bag.
