Those two cases are orthogonal — one doesn't exclude the other, and I'm  
not claiming that it solves the "art-directed" case.

In fact, even if you have adaptive cropping of the image, you'd still want  
image resolution to match display's DPI, e.g.

obama-face at 2x.jpg vs obama-with-audience at 2x.jpg

and possibly negotiate on both axes at the same time:

obama-face at 2x.jpg vs obama-with-audience at 2x.jpg vs
obama-face at 1x.jpg vs obama-with-audience at 1x.jpg
