Have you not seen the extensive discussions between the Faster CPython people and the PEP 703 people? There’s already a lot of debate about how 703 impacts the performance work. Your proposal is way behind where they are on that.
You don’t need to guess, there’s an extensive discussion here. And PEP 703 will be a bunch of extra work for the faster CPython team. So it’s far from no longer mattering.
Fair. But I doubt there would be any appetite for another run at the GIL for quite some time.
It’s not so off-topic that it’s inappropriate, I didn’t mean to give that impression. But it is unlikely to generate anything but speculation. If that’s all you want, then fine.
