Because it would cast into stone the way to schedule threads. OSes use
very finely tuned heuristics (for fairness, priorities, locality, etc.)
to schedule threads, which we do not want to see hardwired in hardware.

Really, all the support you want to get from the hardware is just
getting the number of processors, initializing them, and support for
interprocessor interrupts (IPI) for signalling.
