It isn't sane, it is an artificial limitation and poor design. At best it was an pre-mature code optimization. It should be fixed by a professional coder who doesn't impose limitations, especially in an OS, based on wanting to fit bit flags into a single variable. Windows should fix this -- there should be nearly unlimited cores per group. They can still have limitations per Windows version so they can price segment their market.
