Many of the gray projects listed never even specify the minor number. Looking at setuptools, they only list Python :: 3. If you go back to https://pyreadiness.

Many of the gray projects listed never even specify the minor number. Looking at setuptools, they only list Python :: 3. If you go back to https://pyreadiness.org/3.8/ https://pyreadiness.org/3.8/ there are 20% of packages not explicitly supported, many from the top 100 list, anyone using these packages know this is not a concern. (Going back even further in versions you start to see dropped support instead) Deducting these 20% should give a more accurate picture, and even then I’d bet most other packages work anyway, like you say.
