I don't recall the specific post from Dr R, but I believe that he and others were only suggesting the use of relatively small bits of metal - nuts, screws, threaded rods, etc - within the field of the primary. The portion of the field intercepted by such small bits of metal is inconsequential. It would be a different story if large chunks of sheet metal were involved.
