PyPI: The HTML representation of the index API is frozen

> New packages and releases will continue to appear in the HTML representation, meaning this has no breaking implications for downstream index consumers.

> The HTML index is essentially a bare-bones version of the human-readable index that PyPI once served, back before PyPI was a resource that installers automatically retrieved packages from. It's that old!

And yet people still have the stereotype that the Python ecosystem is in the "move fast and break things" camp. It's frankly infuriating.
