> I would much prefer for these pixel shift modes to produce an image where each pixel has an RGB value associated with it, rather than yet another Bayer image that's just bigger.
I know that's one way to do it, I was under the impression that for some reason it was being used by some cameras to increase resolution only to ultimately produce a bigger Bayer image. I'm probably wrong since I haven't been able to find cameras that do that.
It depends on the implementation but that's what pixel shift is for, you get full color information (essentially negating the bayer filter by moving the sensor 1px up/down/right/left): https://www.pentaxforums.com/articles/photo-articles/how-pen...
