My allergies have hit me hard so I'm not thinking at full capacity, but did we ever decide if supporting os.PathLike in the stdlib was viewed as an enhancement or bugfix? Specifically I'm thinking of https://bugs.python.org/issue30218 for adding support to shutil.unpackarchive() and whether it should be backported to 3.6.

On the face of it, that particular issue looks like an enhancement that should have gone into 3.6 (if ever), but did not. I notice that https://www.python.org/dev/peps/pep-0519/#implementation did not include "Update shutil", so it was not done, at least not completely.

Was shutil updated at all? Is unpack_archive the only shutil function not updated? If so, I could see the omission as a bug.

If the patch for 30218 were applied in 3.6, would the doc https://docs.python.org/3/library/shutil.html#shutil.unpack_archive need to be changed, with a note "Added in 3.6.2: filename can be any pathlike object"? If so, it is an enhancement.
