Just because there are wheels doesn't mean you'll never need to install Rust to install Cryptography. Just this week I got a "you need Rust" build error inside of a Docker container due to Pip not being able to find a wheel for the specific Python version used by the container. Fortunately, the version of Cryptography that was being pulled in supported that environment variable to use the C version instead, so I was spared from having to do a ton of work.

For now. One day I'll wake up and a future version of this container will refuse to build because whatever library pulled pyca/cryptography in got upgraded and now needs the Rust-only version.
