Yes many people do reduce development when they add exposure, it is even part of the normal instructions given by Ilford and Kodak and Fuji.

That doesn't mean we really should.

What I want from a print/scene doesn't change with the rating I use to shoot the film. If my expectations of the scene and for the print haven't changed there's no reason for me to adjust development, in essence there isn't a more useful curve/contrast rate.

This does assume that I know what contrast rate I want, and I normally do, that doesn't mean the OP does. All of us are just taking wild ass guesses as to what will workfor him.
