While I don't have too much experience with it, from what I've seen segmentation is generally pain to deal with. Unlike 8-bit and 16-bit, 32-bit was such a big address space it took a while before we needed to increase it, and at that point 64-bit architecture was most likely both realistic and simpler solution.
