Its primary purpose has been as a fallback on a system where the shell
is working but nothing much else is.  Hence it provides the limited,
easy-to-implement things you're likely to need to fix what needs
fixing.  Moving things between file systems typically isn't something
you need (though in any given case it may be, as well as a whole load of
other stuff the shell doesn't provide).
