Costlier than blitting of the whole screen? ;)
I didn't test this implementation for performance, but in other browser on symbian there is clear difference for big plugins that do partial screen updates (like some animation running) on N8 with raster only flash plugin. Frame rate drops significantly and visually you can seed difference. With HW accelerated plugin difference is minmal (5% max for small animations on full screen plugin), but still exists.
