That is if the camera has an electronic shutter. Also the user is really not allowed to move the camera at all (unless the SR balances it out). We are talking about very small movements that can ruin the effect, so I think it is safe to assume that this really mostly makes sense for tripod use.

The data doesn't have to be processed in camera. I think those who are this particular about image quality wouldn't want to have to use JPEG.
The Foveon mode intrigues me more. That could be done in camera, and quickly. Just add up the values taken for each pixel in each color (with 3 photos, maybe 4 or 5 because I believe green is bigger?) and save it into a raw file. The file wouldn't be much bigger, but have accurate colors, no moire etc. Again the subject does have to be very stationary.
IIRC Sony has a sensor that does this on the fly, and so fast that it works handheld or for video.
