I noticed that, and it puzzled me. How does the inclusion of film
contribute
in any way to answering the question that motivated the exercise?
Which, I
believe, was "Do you need more than 12 megapixels in a full-frame digital
sensor?"

An indirect relationship to be sure, but if somebody submitted such the
comparison could be of interest. A 4000 dpi scan of a 35mm frame is
about 21.5 Mpix. So comparable in pixel count.

Comparable in no of pixels, but not in quality - I've never seen a 4k
scan showing any better pixel-level quality than about an 8Mp dslr
equivalent (given nyquist/aliasing, etc).

Surely you would need the proverbial (and rarely seen) *good* drum scan
(and probably only from K25/Velvia/b&w) when you are getting into this
territory..?

Pushing past the extremes of 35mm format, imo, but it's interesting.
