I'm not sure I understand the dislike of the system. In every car I've driven with that system, the engine starts instantly while moving my foot from brake to gas pedal. It is essentially no different than if the engine had stayed running. At all. Move foot - go.
As far as adding wear, I doubt that can be computed over the life of the engine. Today's engines are good for 300,000 miles at least. If start/stop adds wear, will you get only 280,000?
Yes, it may be of zero help with the climate, but the whole man-caused climate change idea is probably false to begin with. So the only effect is to save you a few drops of gas at each stop. That's not a bad thing, is it? Maybe it's only a gallon a month, but with all the cars out there, that's a shipload of gas.
