I already mentioned that details smaller than the specified superpixel
size would not be detected. Isn't that what you're talking about? If you
choose to render with 8x8 superpixels, then a 6 pixels wide sphere
easily could get lost. However, the border of a 100 pixels wide sphere
would be completely sharp - wouldn't it?

So certainly, the feature would not work well for some scenes with very
small details, but for many scenes I think it would work brilliantly,
especially if you keep the superpixels reasonable small, like 4x4 or 2x2
(which would still give a huge speed-up).
