You're right, that is certainly one option. I think the member asking about the roots-style supercharger was interested in the look of the earlier models. They do look great but come at a size, weight, and H.P. hit (due to parasitic loss). My twin screw requires 1/3 of 1 H.P. to run. A traditional roots style requires 25 H.P. or more depending on supercharger size. Roots style also generate more heat.
