If you do, you block the effect of the apodizing element and it becomes a normal 135mm lens.

That is irrelevant because you're effectively striving to maximize DoF. Apodizing element is primarily to help towards a gaussian rendering of OOF areas, when they are to show up.

So are we agreeing that when stopped down, the 135mm STF is just a normal 135mm lens?  Pretty much all lenses can be stopped down about 8 stops from maximum so "ability to stop down" means nothing.

Shallow DoF is a consequence. Getting a 500mm f/4 has more to do with maximizing speed than to create a shallow DoF.

Here is a way to view arbitrary images from a set of ~65k photos using the Canon 500mm f/4 lens. http://www.pbase.com/cameras/canon/ef_500_4is.  How many appear to use a blurred background as part of the composition?
