This is fine if the guest hasn't already brought the vCPU online, but if it has, blocking CPU_ON doesn't prevent the guest continuing to use the vCPU. How would that aspect be addressed with your approach?
CPU_ON shouldn't block, but can (now) return DENIED if the firmware policy means the CPU is "pretend not-present".
That is what I meant. Not "block" as in "wait until something".
