Update: I've been talking to the Python Packaging Authority and they basically say that if you want to install files outside of a Python module or the limited files they support then use a non-Python build system like autotools/Meson/etc.
"Given that setup.py install is deprecated and will not be un-deprecated, developers of Python software that performs Unixy integration are advised to migrate to a non-python build system."
