Fedora 28 introduces the ability to use an automated Python module dependency generator for packages that provide Python Egg/Wheel metadata. Automatic generation of Provides has been enabled in Fedora since Jun 2016. As a result, all packages that include egg/wheel metadata now have their Provides entries added automatically. With this release, packagers are able to take advantage of automatic generation of Requires entries, removing the need to specify runtime dependencies manually.
