It would be a tad more accurate to say that the Rodenstock uses LTM -- Leica set the pattern in the 1930's by building enlargers which took the camera's lens as the enlarging optic. Other manufacturers simply adopted the same thread -- 39mm by 26 turns-per-inch Whitworth -- for THEIR enlarger lenses. I believe that only Schneider and Zeiss resisted this in recent years. The Summitar will be adequate but not stunning: a taking lens is designed to meet different optical conditions than is an enlarging lens.
