If one needs Rust, C/C++ level of performance I doubt there is much Python can do and one can wonder if Python was ever the right tool for such a project.
If you expect to need the performance of a statically typed, compiled language I don't see why you'd prototype in a dynamically typed, interpreted language.
That's why build systems still look like black magic infused with even darker sh, and a bit of perl sprinkled all over, presumably because the previous maintainers were all out of goat blood.
