source for Python version metadata?

[neuromusic]

There are two available sources

“Python_requires” in PyPi (looks like “>=3.7”)

• This is what pip relies on to decide whether a plugin can be installed, so we can be fairly confident that plugin devs are keeping it up to date
• Would we want to parse it to provide an explicit list of versions? E.g. “>=3.8” would become “3.8, 3.9” and filtering on 3.7 would exclude this plugin?

Trove classifier in PyPI (looks like “Programming Language :: Python :: 3.7” etc)

• This is what shields.io looks for (see https://shields.io/category/platform-support)
• When a new version of Python is released, plugin devs would need to manually tag their plugin by adding another trove classifier
