No, index is the protocol for "do a safe coerce to integer". The name is misleading, but its use in non-indexing contexts is well established. E.g.

" ab" * obj will return a string with obj.index() repetitions. A good argument for Chris A's proposal over on python-ideas to have a dunder method for "coerce to a lossless string", that could be used for Path, but also for who knows what else?

As I see it , exactly the same as the fspath idea, except that we'd use a name that made it clear you might want to use it for other things (and str would grow that method...)
