Hello Lee and Lev,

I requested that back in 2007. I even added a possible was to used it 
as an alternative for background-size [1].

I got a compromised solution for being able to position a background 
image from the right and bottom edges by adding keywords. This is now 
in the spec which is currently in LC (Last Call) status nearing PR 
(Proposed Recommendation).

It may have been different but unfortunately background-position 
initially allowed a different axis to the margin and padding 
properties. An example showing margin and padding done in shorthand 
with two values.


margin: 0 0; /* vertical and horizontal */
padding: 0 0; /* vertical and horizontal */
background-position: 0 0; /* horizontal and vertical */
