If you want to align virtual content with the real world in any way you need a camera attached. Sure, you can use the display for notifications and content that doesn’t care where you’re facing, but having a display attached to your face is a too juicy scenario not to do more with it.
I like the concept of having a display in your glasses. I just don’t fathom why would you also put a camera on them.
