I think mgorny is aware of that; he’s been active on the relevant DPO threads.

(At the end of the day, this is exactly what support tiers are for. CPython, at least to my eyes, has been very transparent about not guaranteeing support for every platform that has a C compiler.)

Yes, optionally apparently but I think we'll end up with forks of Python if the Rust enthusiasts push it any further. I think the option will be off for me.
