Yeah, that's what I was suggesting when I brought up text-fill-color.   
It would serve as a fallback color inside a text-fill shorthand just  
as background-color does inside a background shorthand.

Yes, applying to the shadow would make no sense if the image pattern  
became the actual contents of the fill.  (You'd see those contents  
cast a shadow when painted of course, but that's a different effect  
when compared to having the shadow participate as part of a mask,  
which is what the background-clip: text option does.)
