The problem is not the length per se.  The problem is that the value is 
not stored anywhere and has to be generated based on other data 
structures, which can be very expensive.  For example, as sane algorithm 
for generating this value will examine all the individual CSS property 
values to determine which of them can be collapsed into shorthands.

As long as the "slow as molasses" behavior is opt-in, not opt-out... ;)
