This may be my ignorance, having an iPhone 7, but doesn't Face ID "unlock" to what everyone previously called the Lock Screen? So not only do you need to point your phone at your face (which, I'm more conscious than ever, I rarely do) but you still have to perform some gesture to get to your home screen where with Touch ID it's one gesture to do both.
If you wake up a 7 and swipe on a notification you will get the touchid dialog. On an X it will bring you directly to the app because the phone is already unlocked.
