That'a decent use case.

A new keyword could fix it. But it's expensive to change the syntax at
this point. How about just changing the stacking order so that the
border-image goes to the bottom? This would allow my code to work as
expected:

     div { 
        background: black;
        border-image: url(picture.jpg) 125 125 125 125 stretch stretch;
     }
