I'm not a big fan of a flag parameter to change the return type of a

getcwd/getcwdb for example. I don't know if it's a good example
I think of os.fspath() as more of a filter/reduce operation:
- str -> str
- str DirEntry -> str
- bytes -> bytes
- bytes DirEntry -> bytes
The purpose of os.fspath() (at least the one I'm arguing for ;) is to
distil its inputs to the lowest common denominator, and no lower --
which is either str for string-based path objects, or bytes for
bytes-based path objects.
