I see the point a bit differently:
there are costs and benefits to the abandonment
of a specific and natural behavior of containers.
(The kind of behavior that arrays have.)
The costs outweigh the benefits.

I never suggested there is.
My question "how to guess?" does not imply that.

My point is: the matrix object could have more intuitive 
behavior with no loss of functionality.

Or so it seems to me.
See my other post.
