Hardly. Libraries that subclass from str will provide their string
representation precisely by being (a subclass of) a string. So they
don't need the __fspath__ protocol, and can continue to work exactly
as now.

This PEP merely provides the same capability for libraries that prefer
*not* to subclass str.
