Can this package be replaced by something else already in Sphinx?

When this package was written, Sphinx was pretty young. Perhaps it has a built-in feature that can replace this package now; maybe https://www.sphinx-doc.org/en/master/usage/extensions/autosummary.html#sphinx-autogen-generate-autodoc-stub-pages ? Or is this not possible because what Sphinx has is not completely automated?

Simon, "... they have https://www.sphinx-doc.org/en/master/man/sphinx-autogen.html and https://www.sphinx-doc.org/en/master/man/sphinx-apidoc.html, but it's not clear to me what it covers and what is missing."

This would supersede #146

Compare this package's documented behavior with Sphinx's autosummary, sphinx-autogen, and sphinx-apidoc features, starting from the linked Sphinx documentation. Determine which capabilities are covered and which are missing; done means recording whether the package can be replaced and how this relates to superseding issue #146.
