Yeah, you're right; given that it's an opacity blur there's no
sensible way to put it in another color space without changing the
color space used for compositing.  Doing compositing in linearRGB
might be a sensible option to offer (SVG offers it), but it's not
connected to the blurring in box-shadow.
