While I mostly agree, I'd like to point out that there are legitimate ecceptions to the rule; for example, one of my winter bikes (which I have now deconstructed) had a diskbrake in the rear. Why? Because in the winter, when you cycle on uneven, bumpy ice, sometimes covered with loose snow, or on very hard-packed (and very uneven) snow, or down a hill on ice (this is Finland), you'll notice that your safety is better served by a rear brake you have good control of, and is dependable regardless of snow, rain or other precipitations.
V-brakes in front were all I needed for emergencies. This setup was the fruit of many experiments and a longtime experience. You might disagree, but if you were in my shoes (that means, going through the finnish winters cycling), you would come to the same, or similar, conclusions.
