OK, let's take the odd-pixel thing out of the other discussion then, and just make sure we say something elsewhere (the spec itself? In the test suite?) that the blur amount should not be rounded prior to actually applying the blur, and that resultant rendering should therefore allow an odd number of pixels as well as device pixel accuracy. .
