Hasn't Microsoft experimented with disabling the JIT for security reasons?[1] Doesn't have much relevance for Python at the moment, but I'm just mentioning it to underline that a modern JIT can be very complex thing and keeping it simple for 3.11 seems like a very reasonable requirement.

That isn't what is being discussed here, every JIT has a potential for eventually generating code patterns susceptible of exploits.
