What if it were pure “archival C” whereby the project maintainers defined the undefined behaviors? And I don’t think it would need SIMD optimizations and such, it’s not designed for performance so much as to keep code runnable. It’d probably require some sort of VM specification too, maybe java is a better choice. keeping the code “alive” by keeping it in a project when it’s never used doesn’t seem like a strong guarantee that it will still work when you need it.
