Quite disappointed with this change. The project was never slow to begin with, and the amount of data it has to process is so small that it’s honestly ridiculous to rewrite it into Rust.
But now that it is not pure Python any more, one can await problems that will arise when trying to run it on a non-mainstream platform. No Windows ARM, no PyPy, no musl+aarch64… The probability of having to compile it when installing is not worth it for a primarily CI-used tool.
