Your not avoiding images. They are already there in the image-border.  
Your just treating resolution indepenance for shadows as though it is  
vastly more important than the designer's choice to sacrifice  
resolution indepenance for a raster effect, and more important than  
having a good fallback plan. It is not. Not by a long shot. You would  
hardly notice the difference for most shadows that are just a few  
shades of gray in a small space.i And none of these particular  
tradeoffs and alternate means of doing things were discussed in the WG  
meeting. The resulting decision was rash, IMO. Nothing personal, but I  
think it is pretty clear that this was not a author-friendly decision.

You'd already be using them for the border. Don't you think authors  
are going to change the image border color on hover over buttons  
anyway? Of course they will. With new (very small). You save nothing.
