Focal length limited applications still benefit from the greater pixel density of APS-C. Example: bird photography. Large-field sports photography. I can get some pretty decent photos with an APS-C DSLR (60D) and 400mm f/5.6L.

The 400/5.6 is not a particularly sharp lens. On a crop camera, even less so. The increased pixel density does not help you so much then. At 640mm equivalent, you will have some camera shake, even on a tripod, and loss of resolution due to haze. All those factors would dominate the resolution, not the pixel density.
