Hmm, discovered python/mypy#5775 |

Also, the stubtest windows tests aren't doing anything (and I think this has been the case for a while, probably since they were moved to Github Actions) |

Should we put this in _typeshed?
There was a problem hiding this comment.
I'd prefer not to... even if it can be made to work, it'll involve a mypy-typeshed dance (and maybe changes to other type checkers) for little benefit.
Plus _typeshed is for making types internally reusable, and PathLike is already internally (and externally) reusable from os

I made PathLike a protocol in python#4447, but it should also be runtime_checkable. Caught by mypy_primer: src/werkzeug/utils.py:646: error: Only @runtime_checkable protocols can be used with instance and class checks
