Well, the primary (only?) reason for matrices to exist is the
multiplication operator. That was unaffected by the current change. I
would say that most of the people in the discussion thought that
matrices should behave as much like arrays as possible, with the sole
difference being the * and ** operators.
Of course, I use arrays instead of matrices, so I'm not particularly
aware of any more subtle conveniences they offer. Perhaps you could
contribute some use cases that demonstrate the utility of the very
surprising old scalar indexing behaviour?
