Comment (by stefan6419846):

This change seems to have removed the `AUTHORS` file from `*.dist-
info/licenses` due to explicitly declaring the list of license files to
use. Is this intended or an unexpected side effect?

Comment (by Jacob Walls):

Thanks -- I was not aware that the `AUTHORS` file was previously included
in `*.dist-info/licenses`. I see the packaging user guide
[https://packaging.python.org/en/latest/guides/writing-pyproject-toml
/#license-files example] includes such a file, so I would accept a PR
adding it to `license-files`. Would you like to do that? You can prefix it
`Refs #35961 -- ...`.

Hi stefan, thanks for spotting this! I was the one that created the
original PR which caused this, I'm sorry.
My new PR for adding back the AUTHORS file explicitly is here -->
