I think the problem is that some of us learned a new way to use the TouchID without using the home button to get to the springboard. So for us it's not the same way as always. On mine and my wife's iPhones, if we were to get a notification and the screen lit up, we could simply rest our finger on the TouchID to be taken straight to the springboard. This could very well save the home button. I'm one the the few that have had to have the front screen replaced due to a faulty home button. I know there's only like 3-4 people on this board that has had a home button break and had used this feature up until iOS 10, but for us 3 or 4, it's important.
I've also made the point, that I can raise my phone to wake it now and if I want to interact with my notification, I can do so with the self control to not rest my finger on the TouchID unless I want the phone to be unlocked and taken to the springboard, but Apple apparently thinks that many others need to have to press the home button I guess. This is backwards from the direction that many other OEM's are going in with adding a touch sensor to their phones to unlock it. I take solace in the fact that Apple wants to be special and different though and that we have the best phone available.
I also take solace to the fact that many people never knew or never actually had the feature that allowed you to simply rest your finger on the home button to be instantly unlocked an taken to the springboard upon receipt of a notification but if you did have the feature, and had gotten used to it since the iPhone 5S (oh, 2-3 years or so), then maybe you'd understand.
