Or just write faster JS using it's lower-level language features. Nothing about whatever collection of build tools the JS ecosystem uses "requires" rust/zig/c++/go for performance. It's a closed text transform problem.

The native languages are easier to get decent performance for sure but, braking the entire ecosystem and a generation of future contributors, for what should realistically be single or low double digit percent gains is not worth it.

You are simply ignoring the history of these tools and why people have begun to reach for the languages in question.
