No use case at all. This is a technical specification, so I write down what
is possible, not necessarily what you'd write in your code. Of course it
makes no sense to write something like ...[1, 2, 3], because you could just
as well write 1, 2, 3 directly. The point of that example is that it's
possible to mix it with normal arguments. The "practical" example for that
is the example in the introduction: $db->query($query, ...$params). Here a
"normal" argument is followed by an unpacked argument.

Assuming you mean call_user_func_array, yes. This is just syntax sugar for
call_user_func_array. Advantages of this syntax over cufa are outlined
here:
