All these names are not descriptive. I wonder how hard is to deprecate all of those and replace them with ANSIBLE_SHARED_FILES? Is that name makes more sense to everybody else?
When dealing with a large project and speakers of 50 different languages not everyone will like every choice.
See the configuration file section of the docs to understand these, we will not be renaming them nor do I agree this is an improvement as it makes something very specific much less specific.
