According to the documentation, tarfile.open accepts a path-like object since Python 3.6
However, it is not the case when writing a compressed gzip (w|gz).
See the attached file for minimal POC
Note 1: tested on 3.6 and 3.7
Note 2: https://docs.python.org/3.6/library/tarfile.html#tarfile.open

This was documented in c45cd16 but it seems a test for opening gzip file with 'w|gz' mode as in the original report was missing.

3.6 only gets security patches. Thanks for testing with 3.7 also.
