Yeah, didn't occur to me until after I'd posted. Math is not
intuitive for me. Still, it seems like an argument could be made for
bigger sensors, bigger photosites even at the expense of resolution.
Although some digiicams seem to be binning now. I assume that's why I
keep seeing low-resolution/High-ISO modes popping up.

There's no reason to assume binning there; they may simply realize that the unwary customer is going to look at the 1/4MP image at half the width on the screen, and enjoy lower apparent noise (along with lower apparent size and detail), and downsample after demosaicing.
