Currently wondering the same as augustya, you originally didn‘t seem to want the home button to be removed but what you said would actually be
in favor of the home button-less design, no? There would be no „upright“ or „wrong“ orientation to unlock it, the home bar to swipe up from would always be on the bottom with respect to how you‘re currently holding the device. For example if you only use the iPad in landscape mode, you could
always swipe up from the
entire bottom of the screen, you don‘t have to reach to sometimes the left and sometimes the right side of the device for the tiny home button and then hit it in the right angle for Touch ID. Or am I missing something?
Also using solely a passcode and no biometric authentication method would still work, just like on the iPhone X, if for some reason you prefer that. But unless you have an evil twin or something, I see no reason why you wouldn‘t want to have your device unlock by just looking at it.
