Considering that they're trying to make it a "world car", IRS is necessary in order to steal market share from Nissan Z's and the like. Which makes me wonder why they don't do a sort of trial run on the relatively low-volume GT500. Roush already has a setup for this-generation Mustang, so why don't they just adapt it?
IRS isn't necessary for anything other than adding another 'feature' on a brochure. A well sorted live axle, which the Mustang has now, performs just as well as any IRS without the drawbacks of easily overheating the diff, snapping axles, and camber gain.
Whether it's blasting stoplight to stoplight (which is what 99.9% of RWD drivers have do/have done) or going around a racetrack; it makes no difference.
Auto journalists are snobs and have to fill their articles with good/bad, something great, something poor, blah-blah-blah. Everything you've ever heard regarding a live axle is probably crap. While simple, it's tough and it works.
Having owned a live axle Mustang with both the OE 'quadralink' and a properly engineered torque-arm/panhard bar, there was a world of difference between the two. No more axle bind and no more snap-oversteer; the rear of the car, if anything, had TOO much grip.
If you're complaining about 'bumpy roads' or 'ride refinement'; go buy a purse to match your new skirt.
