You'd be surprised how many people around the world make do with an Android or Apple phone. I would think, as long as there is an option to either browse the 2600+ directory through a USB C/or B to C adapted connected device and drop any downloaded firmware there, or have it on external flash device (have it be the only file or have an appropriately set up folder system) ,then flash/boot it, things would be fine.
I have a feeling, though, that it needs an active external push, through proprietary software.
