I'm not sure exactly what you mean by "over-indulgence in skeuomorphism". However, if you're suggesting that the previous trend of almost photorealistic visual styles could sometimes become too detailed/cluttered/noisy or that UIs in that style sometimes lost cohesion because being photorealistic was about the only thing a lot of the iconography and window dressing had in common, then I would agree with both of those points.
