Oh but I think it is. Why do people think their current phone does everything they need? Because it has a headphone jack and Touch ID home button. Face ID is not a reason to upgrade. The lust people on this and other forums had for a "bezel-less screen" doesn't matter to 90% of people.I think its more the thought that "my current phone is working perfectly fine and there is not enough reason to spend $750+". Headphone jack and home button are not an issue for the vast majority of people.
I only know 2 people that have an X style phone. No one else wants to give up the headphone jack or Touch ID home button. Also, point 3 is the price. $750 for a 6/7/8 Plus style phone with 256GB storage, Touch ID home button and a headphone jack would sell. I think it would outsell the XR.
