Thought never occurred to me...

While a rangefinder will encourage you to focus just as accurately.
Then put a slight telephoto on an SLR and start taking portrait photos. It's just pure fun. While the rangefinder with a telephoto just seems like a kludge. The M2 did a good workaround by moving the framelines. But my Contax didn't - requires accessory finder or guesswork.
