I think there is a contradiction between this example page in the documentation and the reference of pytest_load_initial_conftests.
https://docs.pytest.org/en/latest/example/simple.html#dynamically-adding-command-line-options
https://docs.pytest.org/en/latest/reference.html#_pytest.hookspec.pytest_load_initial_conftests
The examples page suggests that it can be used to " dynamically modify the command line arguments ". But the reference says This hook will not be called for conftest.py files, only for setuptools plugins.
The examples page doesn't mention anything about setuptools plugins and it gives the impression that it can be used from conftest files, like other examples from the same page.
