All the V-Cache parts are currently premium parts. Dropping the L3 from the underlying CCD chiplet would force them to incur the extra 3D packaging costs on all the products using those chiplets. It would also put the V-Cache directly over the CPU cores, where the current products only stack V-Cache on top of the L3 portion of the underlying CCD. I don't expect them to make this kind of change anytime soon.
