I believe it was for energy saving purposes. The reasons were for better and more efficient power supplies, not having multiple voltage outputs with multiple current ratings, etc. I'd be happy with a separate tier of PSU that has the standard 12v rails, but also includes a rail with 36 or 48 volts for dedicated GPUs. The less amperage running down those slim wires, the better...
