Very true. Still, the harness' can be connected and if for some reason you need to have it flashed before it is recognized by the car, it can usually be done for a minimal charge at the service center.
No trying to rain on anyone’s parade but the 5 seater has no heat or AC in the rear like a 6 or 7 seat model X. It’s the same problem with the jump seats in the back of the S is that it becomes a sauna in the rear without ventilation. It might be ok on short drives or on nice days. This would be nice if someone already owned an X with 5 seats and wanted more versatility but I think it would be better if buying a car to get one equipped with AC and heat.
