Perhaps, but it does certainly help in determining what kind of performance one is seeking, because you often need to trade startup time for run time when it comes to DOM manipulation. You either have a large framework that takes longer to load, but keeps you away from direct DOM manipulation (for the most part), or you don't and suffer the performance effects of constantly reading/writing DOM property values that trigger layouts/repaints.
