The use case is the expressive artistic power you put in the hands of designers, to create a much wider variety of adaptable, animatable designs that aren't possible today. I've been wanting this power for drop shadows since I proposed it back in 2009:

Note the inclusion of border-image as the border part, too. We were told at the time that SVG 
parameters combined with filters would solve this soon, and I've been waiting patiently ever since. 

It would be equally powerful and welcome to be able to do that sort of dividing up/layering the effect with opacity, too.
