Shortening CSS property names isn't a strong use-case.  Names are
usually already as short as possible while still being understandable.
 Shortening them further just makes them harder for others to read.

More importantly, one of the big reasons the CSSWG finally accepted
Variables is because it offers powers that you *cannot do* with a
preprocessor.  Rewriting property names can totally be done in a
preprocessor.  You actually *want* the limitations that a preprocessor
provides here - you *really* don't want a variable you're using for a
property name to change based on the element's position in the tree.
That's just confusing as hell.
