And that! is only when you look at it from the rider's point of view.
From a coach's point of view, implying that you have to manage many different programs having their own flavor in term of season's goals, periodization becomes more a matter of management, than peaking.
There is an other intesting thread on the subject of peaking. It has been opened by YMCA.
With certain athletes, I favor setting season's goals on some sort of a ranking. Could be provincial (state) cup, world cup and such. Usually, there are many races involve. Add to this a major championship, plus its qualification, you end up with a busy racing season. Management is the key to perform well and meet the goals. Peaking? Hmm well, it depends. Could be 12 even peaks, I don't mind, as long as the athlete is comfortable with it.
But with certain other athletes, long distance, the goal are based on very difficult events (Ironman triathlon, marathon, multi-stage cycling). Long distance Triathlon World Championship, held in Hawai, is an event that last between 9 and 11 hours. That is 180k TT in aero position, under heavy hot sun (over 100degrees), followed by a marathon. These events need to be treated with all due respect. In that case, proper periodization is a must, peaking is an absolute necessity.
