Python

The value of cargo and go tools doesn’t come from the all-in-one nature of them, it comes from the official nature of them.

If something doesn’t work with cargo, it is a bug. Period. There isn’t any “it works with pip” back and forth arguing over whose fault it actually is (package? Or poetry/pipenv/pip-tools/conda/etc? This happened with pytorch a while ago, and I’m not sure if poetry and pytorch get along even now)

There also isn’t any debate over project files or configuration stuff — Pyproject.toml vs setup.cfg vs random dot files in the project directory — if you are a currently developed project you support whatever cargo supports and you move to support the latest format rather than dragging your feet for years (pyproject.toml has been the “next thing” for python since 2016! And is only finally getting widespread support now… 7 years later).
