I think it has been mentioned previously in the list that text-shadow 
was spec'ed before spread radius was added in box-shadow. Thus, the 
text-shadow definition
assumes 3 lengths, even though it doesn't explicitly restrict 
text-shadow to 3 lengths. So, technically, a spread radius should be 
allowed but the way it should work is not specified anywhere (there was 
a recent discussion about spread radius in text-shadow: 
http://lists.w3.org/Archives/Public/www-style/2011Feb/0796.html ).
The only UA currently implementing a spread radius in text-shadow is 
My point is that the issue you are pointing out with the text-shadow 
definition is actually part of a much bigger one.
