Full Frame 35mm is simply more demanding on lenses, and requires more

Not entirely, on a pixel for pixel count basis an high density "APS-C" sized
sensor also requires a lens of approximately 1.5x the absolute resolution to
achieve the same resolution in print as a FF (36x24mm) sensor.

While that is technically true, it's not a major issue because those
sensors are right in the 'sweet spot' of 35mm lenses, and most 'Digital'
lenses aren't a whole lot smaller, for edge-performance reasons. Edge
performance issues on 36x24mm sensors will far outweigh the extra
resolution demands of the similar-MP APS-C sensor at the current time.
