Why do you think the S5K3J1 is an upgrade? In terms of size it's almost certainly smaller than the IMX586 with the latter matching 12MP 1/2.55" with 48MP, now this is 10MP, to even match that size it would need >1.4μm pixel pitch. Highly unlikely.
I guess the question about the crop module of the S20/21 is if it would output 64MP at "1x", 32MP at 1.4x, 16MP at 2x etc because we've seen that the output quality at 3x is actually comparable to dedicated modules, so if it could read out the whole sensor (rendering the "main" module largely redundant, granted) then that's actually a very unique feature that comes closer to matching the quality of true optical zoom compared to a small optically cropped 3x module.
It's mostly the idea of having two dedicated zoom lenses, instead of the 4x optical + digital on the S20U.
Perhaps that was badly phrased.
And yeah, in hindsight, criticism of the 64 MP on the S20 and S20+ was a bit overstated.
