To make it compatible to 'background' seems to be less confusing. So at the end it is a consideration between compatibility to 'background' and the sense of certain features. I can understand that you would be in favor for a meaningful feature (I would as well). Please give me some days to find meaningful use cases as well as real usage of these properties.

I think it would be more useful, powerful, AND simpler to understand and remember, if we just had the keyword "mask" that we could add to 'background', 'background-image', 'border-image', or 'border-image-source', to clip all element layers above it and all of the element's content and children. 

I think it would also be nice if box-shadow followed the edge of the 50% opacity point of the masking image (or the intersection of that shape and the element edge, actually, for background images).
