Hopefully as Apple's own N-series Wifi chips mature and get rolled into more products, they will include GPS/GNSS capabilities into the chips, as right now if you want that functionality you have to purchase the "Wi-Fi + Cellular" variant:
Edit: to perhaps make it more clear, I meant still sell a +Cellular variant with the C-series chips (or whatever), but move the GNSS functionality into the N-series chips. So you'd have a non-cellular and a cellular, but both would have GNSS.
