Yes, I'm basing everything on the DOZENS of reports that Apple struggled finding a way to integrate Touch ID under the screen and that they eventually abandoned it in order to not delay the release. Since you refuse to believe they were, let's flip it around: If their first choice all along was Face ID, why even bother with something that challenging (Touch ID, under the brand new OLED screen), all the way up until to months before release???? Why not start touting Face ID as the "future" from day one? Pretty obviously: because this is RETROACTIVE spin. They didn't want to use it, they simply HAD to use it. Why is that such an unbelievable thing to accept given all the leaks/reports?
And as far as the earpiece, front facing camera, and proximity sensor, those at MINIMUM would have taken up less space (so maybe a tiny "divot" on the very top of the screen) OR could have possibly been relocated to the extreme edges. They just don't take up much space, especially in comparison to the full Face ID suite of camera, dot projector, and IR illuminator, nor (with the exception of the ff camera) do they need to be precisely located like the Face ID components do. Again, it's fair to say even if they couldn't relocate any of the NON-Face ID components, the remaining real estate needed would be smaller, leading to a less obnoxious notch.
The million dollar question remains:
If you could choose Touch ID or Face ID (and everything else was equal), even if there was NO notch, why would the VAST majority of people choose Touch ID? Some of that is familiarity, sure, but it's also because Touch ID wasn't broken to begin with.
Apple (and the great "designer" Ive... who was great up until about October of 2011, then for some reason, not so much...) have sold a bunch of people on a white lie that Face ID is somehow vastly superior to Touch ID, and how it's a feature that should somehow compel you to buy the X.
They are MASTERS of spin
