Many of the tempfile modules' classes and utils could maybe return Path instead of str. I'm not sure how disruptive that would be, but I would definitely welcome something that avoids having to wrap everything in Path.
I think they might need to return a "StrPath" for compatibility, but IMHO only for some transition period. It is relatively easy to call str(p) whether p is a string or a path if you actually want a string.
