I'm sad to say that there are was also a confusing decision to rename some packages such as "platform-python-coverage" instead of the old name "python3-coverage", matching the python2-coverage which still exists. I've no idea why someone specifically chose to violate that naming convention, and it had to be a conscious choice.
Be aware that there is a minimal python installation (called platform-python) that is used for platfrom/system tools like yum.
But this minimal python installation should not be used for anything else and thus there will likely be other packages with python{2,3}-* naming, as the platform-python-coverage will not be usable for the regular python installations.
At least this is how I understood the split from the blog posts.
