On macOS 12.6.6. Basically, it's marking anything with a leading '/' as invalid.

That is because platform argument defaults to "universal". universal means that check if the file path is usable on any OS. File paths starting with / is invalid for Windows. The return value will be True if you set platform keyword argument value for any of "auto", "POSIX", "macOS".
