package_data_spec not supported anymore?

[martinRenou]

Being able to pass a package_data_spec to create_cmdclass was quite handy to be able to include package_data as part of the wheel, but it seems to me that it's not supported anymore, or maybe I am missing something?

I am not sure I understand everything there, how should one include package_data in the wheel now? I can see we can still use the MANIFEST and include_package_data=True to include data in the source dist.

The standard way: https://setuptools.readthedocs.io/en/latest/userguide/datafiles.html

We provide a get_data_files function but recommend people use setup.cfg for non-glob-pattern data files.

Under the main use of globbing a bunch of folders, I assume get_data_files should do it, but what is the recommended way to ensure that this is only called after the build commands have run ?
