Full Screen apps do not use notch space as seen in their full screen demos

So they're not really "full screen" any more? Why even bother with the feature, and just switch it to "maximize" instead?

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.
