> I suspect this would look highly unnatural in practice
In pair tests test subjects were unable to see a difference between the foveated image and the normally rendered one. The flicker can be removed by blurring the image to the point where flicker no longer exists. Because your brain is used to a very low sampling rate outside the fovea, it actually helps in hiding the artifacts, because they occur naturally in your vision.
