I'm probably damning your idea to an instant rejection from Brian by agreeing with you, but I have stated before that we 'nearest-corner' and 'farthest-side' are not that useful. The only time you can see the difference between them and 'cover/contain' is when the bg-position is off-center, and you see them get clipped in generally un-useful ways. 

If we had only 'cover' and 'contain', AND changed 'contain' to mean "contain within the sides that you are not moving towards via bg-position", then you would be keeping it both useful and simple, and would continue to let authors get the most popular combinations of side-based and corner-based sizing and clipping.
