I agree entirely. It's not like JWST components were built from diamonds or something where the material costs dominated the budget. It wouldn't surprise me if there were already more than one made for many of the bespoke components used in the telescope. Nobody makes a one-off component without some iteration and covering of their own ass in case something goes awry in shipping or assembly.
