Question about pkg_resources.compatible_platforms on macOS

[dataflake]

Please correct me if I am wrong, but it has been my understanding that the OS version string in a macOS binary egg name represents the lowest OS version supported. So for example, an egg named zope.proxy-4.6.1-py3.10-macosx-10.9-universal2.egg supports macOS 10.9 and higher.

With that in mind the code in pkg_resources.compatible_platforms feels wrong. In my particular situation the "provided" platform from the egg is macosx-10.9-universal2 and the "required" platform of the OS is macosx-13.0-universal2. compatible_platforms will reject anything that doesn't match exactly. Should it not accept "provided" when the "required" version number is equal to or larger and the platform part matches?
