Research direction
Start by reviewing linked PR gh-136366 and the datetime module's Python and C implementations; the issue identifies a mismatch in which method parameters accept keywords. Compare the affected method signatures and verify that the positional-only behavior is consistent across implementations before checking the relevant datetime tests.
