This is a notable improvement if you end up mirroring PyPI's artifact structure in a different index, and end up with URLs like https://files.pythonhosted.org/packages/29/a2/d40fb2460e883eca5199c62cfc2463fd261f760556ae6290f88488c362c0/pip-25.1.1-py3-none-any.whl that end up being really verbose for long install sessions.

I'm a little worried that this will lead to user confusion when multiple indexes are in use and pip downloads packages from several indexes1, but I suppose it doesn't matter too much in practice. They can still enable verbose mode and get the full URL.

Could you add a changelog entry? Thanks!

Footnotes

  1. We had an issue filed because pip was downloading full wheels during dependency resolution. The root problem was that they were using a third-party index which had not implemented PEP 658 yet. ↩
