auto-protect parent directories

Is `safe-rm` still being developed?

I've a feature request. Say we have a file, /home/user/dir/file. If I make `file` safe, it is protected. However, I can still delete one of the parent directories (home, user, dir) and lose `file`. Would it make sense to "auto-protect" parent directories of objects (files or directories) that are listed in safe-rm confs?
