As oh right now pkg_resources is part of setuptools, it’s only the downstream
folks who split them apart. There are some decisions to make regarding splitting
them out that I don’t know how setuptools wants to handle it.
However once the stuff that pkg_resources provides is standardized it will be
available as part of https://warehouse.python.org/project/packaging/ so projects
wishing to use the standards based functionality (most of which is heavily inspired
if not outright “stolen” from setuptools/pkg_resources) will be able to use that
