Well the path class is named WindowsPath, not NTFSPath. In other words,
it embodies path semantics as exposed by the Windows system and API,
not what NTFS is able to do. Having per-filesystem concrete path
classes would quickly grow of control (do we need a separate class for
FAT32 filesystems? what if Windows later switches to another

The PEP already points to a corresponding discussion:

What I know is that if I save a something.PY file under Windows and then
double-click on it in the Explorer, it will be launched with the Python
