That's an interesting use case. I guess there's a class of users who are smart enough to want to manually copy/backup files but not smart enough to know about hidden folders or standard directories. Windows has a similar situation with its hidden AppData directory, and Unix with its hidden dotfiles.

I hadn't given this much thought but now I am disappointed that the people who came up with these standards didn't do more UX research and trial & error with actual users. Perhaps if they paid attention to all the use cases and stakeholder needs it wouldn't be such a mess.
