All my bicycles are set up "moto" and my daughters also ride this way, my wife is left handed and likes the conventional North American set up for her brakes.

My older British bikes came set up this way, the rest have been switched over or built that way from the start.

If you know how to brake there is not much risk in going over the bars no matter which hand is operating the front, it is a newbish mistake and something experienced riders don't do.
