Note that Inkscape differs from Batik only after you add rotation. For non-uniform scaling, Inkscape emulates Batik's behavior by scaling the x and y deviations of the blur filter when applied to a scaled object. However, such emulation is not possible for rotation or shear, hence the discrepancy.
After looking over the standard for a while, I think Batik is correct.
Everything I see implies that the effect parameters are in the object's own coordinate space (or, given primitiveUnits="objectBoundingBox", a transformed bounding quad based on it).
