Again, interesting.

Do you think LibRaw is working on the Bayer quads the way it should?

It seems to work properly.

But think about that a 2x2 square has 2 green pixels, which have a centre of "mass" at the exact center of the 2x2 square, but those lonely green and red pixels' centers are not aligned with the 2x2 square's center, thus causing a chromatic aberration-like effect (though it's not too serious, but it's still there).

Good explanation.

Hogan is less than complimentary, perhaps for that very reason, about the method here:
