Multiple pathlib rules recommend the use of pathlib.Path over their os equivalent even when they're used with a bytes string or directory descriptor which aren't supported by pathlib.

One such example is

import os
os.listdir(1)

$ ruff --version
ruff 0.11.7
$ ruff check --isolated --select PTH208 t.py
t.py:2:1: PTH208 Use `pathlib.Path.iterdir()` instead.
  |
1 | import os
2 | os.listdir(1)
  | ^^^^^^^^^^ PTH208
