My point is really that of Douglas Self who is the author of the Audio Power Amplifier Design Handbook, to name just one source. Doubling the output device complement nearly halves THD (a measured effect which is consistent with mathematical averaging) and greatly reduces crossover gain wobble, while also spreading the effect, thus generating lower order harmonics. Reducing the crossover distortion of an AB amp is a big deal. The only downside is in the control of parasitic oscillations.
I understand your theoretical point and think the escape from it which you posited is correct.
