100% agree.

A good compromise that allows for narrow depth of field, wide angles, relatively small camera bodies -- albeit without the ability to shoot as narrow depth of field as with full frame and with a stop worse noise control.
In practice it doesn't allow for more depth of field, it doesn't allow for wider angles. I think we'll find in the next six month that the camera bodies aren't much smaller, either.
The bottom line in my view is that APS-C is a cheaper camera with cheaper lenses, if your image quality requirement is X.
APS-C is a cheaper camera with more expensive lenses, if your image quality requirement is Y.
FF is a more expensive camera with cheaper lenses, if your image quality requirement is Y.
