The problem though as I see it, blipping the throttle has little? effect on rpm matching with upshifts, only effects the torque that keeps the dogs locked, on downshift the only rev matching it seems to me would be if transmission went effectively to neutral while rev matching took place by letting the engine rev before reengaging. Seems risky, uncertain and problematic at face value, pun intended. It would be IMO interesting to see the results of instantaneous rpms of the engine transmission that is happening during these types of shifting events overlayed with throttle position.
