Consumers don't care about physics! The in-camera crop
of the smaller than nominal fullframe sensor yields on
the memory card the same effect as cranking up the enlarger
head to project just the cenrtal area of a regular negative.
That cropped image is what the see and what they get. Again,
DOF, resolution, etc are not part of my point - just that
the end result on the media has a longer reach.
