Obviously but I bet someone in the future will decap future "vintage" random chips to determine if additional cores exist and/or can be unlocked. Dial-a-yield configuration and bin sorting are how yield is maximized and supply chain SKUs are minimized which aren't precisely optimal on individual examples.
