What is lost in the MDS or start/stop technology debate is not just the MPG gains even if so marginal to not be noticeable or non existant, the EPA also imposes Greenhouse gas carbon credit system. With MDS engaged and the engine having only 4 cylinders not being used, there is still in theory a 50% reduction of emissions. Spread over the number of vehicles sold with that system adds up to many total carbon credits the vehicle maker can claim.
In a non regulatory environment, no company would add and keep that level of complication and extra cost MDS brings to manufacturing. In many ways, one can see why the V-8 HEMI and the like are being pushed out with DI and Turbo coming in, it is more cleaner for emissions.
