It would also just be good PR at this point. They could easily spin it as "We could make it work like the others with only cameras, now we add back more sensors to improve even further!". Camera-only has been criticized prominently for so long too, it would undermine a lot of the negative arguments people make too. It would honestly just be an easy win for them, even if there is no real improvement at first, they can even take their time to update the software over time.
