I disagree. The home directory is more like C:\ on Windows. As I mentioned in another post, there is no specific equivalent. Each user chooses to put documents in various subdirectories as suits their preference, so there isn't a good default on POSIX systems. Some desktop environments provide an equivalent, but as there is no standard even among those, it is still up to client code to determine the best equivalent, if wanted.

I disagree with your mappings. I think leaving undefined what has no standard definition is superior. Also, temp_path should be taken from the environment before using a fallback like /tmp.

This gets one into even more proprietary directions. A Desktop "folder" assumes a GUI which isn't necessarily the case on a POSIX system. The AppData "folder" on Windows has no equivalent on POSIX systems. /etc is not appropriate as the user won't have write permission unless root. If such were to be supported by Filesystem, the best behavior remains leave undefined what has no standard definition.
