It has already been reported and has been on the list of known bugs for a
while:

BTW, here's a tip to get smoother results:

You don't have to scale the bumps very small. Try to scale them very big
instead. I tried to render your example code with 50 samples. Then I scaled
the normal 100000 times bigger and now the blurring was much more smooth.

I don't know much about the 3.5 patch, but, what if I want to apply a
surface normal on top of reflection blur?

I imagine this would help:

	#declare tert = pow(numiters,1/3)-1);
		...
	#while (ix<tert)
		...
	 #while (iy<tert)
		...
	  #while (iz<tert)

Either add it to the average or use a layered texture.

Is there a way to specify more blur? Is 'numiters' the amount of blur in this
case? I've tried making the bump size bigger but that didn't work - the bumps
just became visible.

Does this blurred reflection affect caustics from photons?
