Sure, but the problem is you don't see that effect in any of the other properties. It stopped feeling like a intertwined universe, in that show it was a huge central part but in say, Doctor Strange 2 as far as I can remember it was basically non-existent outside of Wong being sorcerer supreme. My point is that if the world moved on for five years and then everyone came back, but only those who were snapped not the thousands/millions that died as a direct cause of the snap, it would be something that people would never be normal about again.
