This is great but you should be aware of the cost. Distributing binary wheels for every available platform (including ARM, MacOS, ...) and implementation (PyPy...) is not easy, and not doing it causes really abysmal user experience (doing `pip install requests` and being told you need to install a Rust toolchain to build `cryptography`). Sometimes the performance might not be worth it.

Thankfully there are GitHub Actions and similar tools that help with this.
