Yes, among other things. You can e.g. have a look at os.fwalk() or
shutil._rmtree_safe_fd() to see that using those *properly* is far
from being trivial.

> You don't like the dir_fd parameter of os functions?

Exactly, I think it complicates the API for little benefit (FWIW, no
other language I know of exposes them).
