What is the use case of using trio.WindowsPath or trio.PosixPath? Looking at the code, it looks like we only wrap methods from PurePath so it's not like they get more functionality (?)

I'm probably missing something trivial though. Though if it's not necessary to then I think having to put platform-specific types is weird for an exported API.

If you look at the pathlib module, that's exactly what they do there. Windows and posix have very different ways of expressing a path (backslashes vs forwardslashes etc). This is making the trio path behavior just like the stdlib.

Practically, being able to make trio.Path a subclass of PurePath means it interops with all other path-derived things, and dramatically simplifies the implementation. However, you can't directly subclass PurePath... you have to subclass PureWindowsPath or PurePosixPath. And that means you need to have to concrete PosixPath and WindowsPath classes.
