Finding a non-artificial example would be important here, given that there are plenty of non-artificial examples to the contrary (cases where env vars are used for arbitrary parts of paths, not being restricted to path components). If there is some incredibly rare situation where that functionality is needed, it can be coded directly in the application. > Let's keep it simple.

I'm +0.5 on paths getting a method for variable expansion, +0.5 for os.path.expandvars learning to return a Path if given a Path (it already returns bytes or str based on the input). Either would work.
