I'm not convinced yet that _we_ shouldn't allow that (well, a shape gradient anyway, as linear gradients only go in one direction). I already bought into the part of the spec that says a specific algorithm is not required, and you haven't yet said anything to change my mind. 

If Gaussian is truly the no-brainer you say, then all implementors will use it or a close enough approximation anyway, with the same results. But I don't see why a UA shouldn't be allowed to create a nice looking blur in some other manner, such as a gradient between two corner softened shapes (if it's ugly, the implementors will hear about it, or users will move to prettier UAs), or why they shouldn't be allowed to blur by other means or maybe put some jitter or noise into the blur.
