Hm, I'm a little in doubt now. I feel the intended method to import is the short version:

from sphinx.ext.autodoc import mock

So maybe we should prioritize that one. If for no other reason then to prevent us being the cause of an import error for the next package.

EDIT: I changed it but let's see what the bosses say over at sphinx-doc/sphinx#14333

FYI: We are still/again seeing this issue with khard 0.21.0, sphinx 9.1.0 when trying to build the package for Arch Linux: lucc/khard#356

I want to merge this try-catch import, I think that should be future proof even if Sphinx rearranged their module structure.
@dvzrv would you have a chance to test this branch on your project to see if it actually resolves the bug?

With pip you can do this with an install like this:

pip install git+https://github.com/sphinx-doc/sphinx-argparse.git@bugfix/autodoc-mock-import
