I just noticed that access to the normal distutils docs has become difficult. They are hidden as "legacy" while a link to the packaging user guide (https://packaging.python.org/en/latest/) is prominently displayed.

The problem is that the packaging user guide is an unreadable mess of recommandations, which is both tedious and unhelpful when you want a detailed documentation of e.g. the setup() function.

I would ask to revert to the "old" distutils docs until the packaging guide becomes up to the task.
