It conflicts with existing Apple design decisions, such as Safari in full-screen with the compact tabs, or Apple Calendar in full screen mode. I wonder how that will work.
They are as big as pre notch. It's just now the toolbar has moved in to a space which was once black bezel. Full screen is still useful for hiding the toolbar for a distraction free view.
Except for purposes of immersion in games and movies, I might just always have the top menu bar visible if the treatment for many full screen apps is just to have an opaque black bar with no content.
