```python
from pathlib import Path
import subprocess

subprocess.run([Path('/bin/ls')])  # Works Fine
subprocess.run(Path('/bin/ls'))  # Fails
```

The problem seems to originate from here:
https://github.com/python/cpython/blob/master/Lib/subprocess.py#L1237-L1240

This file auspiciously avoids importing pathlib, which I'm guessing is somewhat intentional?  Would the correct fix be to check for the existence of a `__fspath__` attribute as per https://www.python.org/dev/peps/pep-0519/ ?
