I suppose this dithering would decrease PNG file size somewhat, because it would increase the number of repeated pixel subsequences, improving the efficacy of the Huffman coding. But has anyone actually done an analysis of how much?
And as someone else noted in this thread, a jpeg would offer better image fidelity and filesize than this dithered PNG.
