Because it doesn't let you have a real pointer to a class.
What is a »real pointer«? Class references are really just
pointers, in a way – you can cast them to void*.
The obvious alternative would be:
auto r = new Bar(); // reference
Bar* p = r; // pointer to Bar; ref implicitly
converts to pointer.
auto pr = &r; // typeof(pr)==Bar** ; can't do better
w/o ref types.
So, does the current scheme have any advantages?
When discussing a language change, the question should always be:
Does the _new_ scheme have any advantages?
