No, the pixel count is certainly critical. Read my premise carefully.

No, the pixel count is not critical. Consider a 24MP FF sensor and a 24MP
APS-C
sensor. The pixel count is equal. However, the pixel densities are
different,
and will contribute to the response characteristics of each sensor, and is
certainly a critical factor in sensor specs.

Your premise is worthless. Consider, it is merely your premise, and has very
little basis in fact.

Photonics Online News
https://www.photonicsonline.com recently ran
several short articles on "Understanding Resolution In Scientific Cameras"
that covered a lot the questions in this thread.
[ You do need to be a subscriber to access the articles. ]


Then it doesnt do us non-subscribers much good. Also, judging by the nature
of the content of that site, I believe an understanding of resolution in
scientific cameras isnt going to help the users of consumer cameras engaged
in fanciful thought exercises in this room, one iota.

OK, i did some searching and found this article that covers a lot of the
mechanics
of the pixel size/sensitivity/resolution basics.

Here's a pointer to the article:

"Pixel Size & Sensitivity"

The relationship between pixel size of an image sensor and its sensitivity
is discussed in detail to illuminate the reality behind the myth that
larger pixel image sensors are always more sensitive than small pixel
sensors.
