If you wanted to do this, I would grab the desktop image somehow, apply the effect to it once, and then use (a shifting portion of) that image as the background of your Source View, etc…. That way there is no need to mess with additional windows, or apply the expensive effect continually. There is the tricky bit (for both solutions) of determining when the desktop has changed (or you have changed screens). It is definitely possible, but requires care to get the edge cases right.
FWIW, I agree with you on the effect. I may be in the minority on this list, but I like the colorfulness of the source lists, and I agree with charles that it seems like waste to spend all that processor power just to get the grey of the window behind it. It would be nice to have a desktop picture mode. That said, I am sure Apple at least considered it, and it is possible that it caused some sort of cognitive issue in testing (e.g. breaking object permanence) which sent things into uncanny valley territory. It is amazing what subtle things can have a strong effect. Filing a radar was the right call, IMHO.
