STINNER Victor <vstin...@python.org> added the comment:
> 5) Remove PathFinder if filesystem imports are disabled
Extract of importlib._bootstrap_external._install():
def _install(_bootstrap_module):
...
sys.meta_path.append(PathFinder)
PathFinder is always registered. So you are not only asking for an API to
customize sys.path, but also to customize sys.meta_path, right?

Would you mind to open a separated issue for this feature request?

Are you asking to format the current exception as a string? Something like
traceback.format_exc() but as a C function?

You're welcome. PyOxidizer is a good use case for PEP 587 (PyConfig). Sadly,
you have to drop support for Python 3.8 and older, or maintain two code paths.
I saw many projects which maintains two code paths: one for Python 3 (use
Unicode and a few other changes), one for Python 2 (use bytes).
