For one thing it would be interesting to learn something about Linux. The command would show what would actually be needed. In my opinion Hey is probably only useful (used) by (would be / wannabe) programmers. For the other thing: I would expect it to do more sensitive things in the future. And also: if it would create a directory where I would it not want to be, it would help to say simply no instead of having to remove it later ('Oh, thats the root where it was created; it should have been the Documents folder').
