It already does. Different UAs are making different judgements about how perfect the blur should be at the higher levels. Some are apparently making tradeoffs for the sake of performance, etc. and others may possibly want to take that further with simpler, possibly non-Gaussian blurs. What I was attempting to was set a minimum level of conformance based on the width of the blur region, and on how different the pixel opacity is at the edges of that region from the areas outside the region.
