Summary

According to the following references:

• https://setuptools.pypa.io/en/latest/references/keywords.html
• https://packaging.python.org/guides/distributing-packages-using-setuptools/#package-data

the usage of data_files is deprecated and does not work with wheels.

Therefore I think the best is to not include it in the main example on the declarative configuration docs (since it may give the wrong impression/idea to users).

Instead the best should be directing them to the datafiles support docs

OS / Environment

No response

Additional Information

The example is particularly controversial, since it includes files to be written to the /etc folder.
