Left foot braking is a very useful technique. It is something I used regularly on my track VW GTis, even if they were MT. I was taught the technique while doing some dirt road rallying. It brings a whole new dimension to playing with weight distribution and the tire friction circles as you can simultaneously use brake and throttle at the same time. As OC3 said, I find it more difficult to do on the M3 as I only use the standard 3 point harness. If I don't brace myself with my left leg, I tend to move around a lot. I still use it in some corners though, especially long decreasing radius turns.
