For those of us that, say, just got a new battery months before this was announced... a while ago (I forget when), there was talk of possibly sharing designs to enable repurposing them as power banks. Any word about that?

Also is there a way of exposing an existing touchpad to that new control board for your external one? (Or keyboard I guess, but the use case is that I had to replace my keyboard too, and for what was available at the time ended up just going with a whole input cover. Truthfully, I was already curious about exposing it to USB-C before hearing about this, and prefer wired anyway, but am also curious about the more immediately relevant part of the question.)
