I don't think those are reasons to make CSS filters simple. I don't think
any significant browser is going to refuse to implement SVG filters
indefinitely. And it is not necessary to keep CSS filters simple for them to
be GPU-accelerated. Blurred shadows are already relatively difficult to
implement on the GPU.

Individual CSS filters should be simple so that authors find them easy to
use. I suspect authors will find it difficult to remember how to use a
function with nine parameters, as you have proposed.
