If root_dir isn't specified then the absolute path doesn't appear:

>>> import shutil
>>> path = shutil.make_archive('testing', 'tar')
>>> print(path)
testing.tar

Maybe this could use a note in the root_dir section, but nonetheless the target branch needs to be main and not 3.10 unless it's specifically for a backport, and would need a new PR as it can't be changed.
