So manufacturers don't add these things to "race" bikes.

Sometimes yes, sometimes no. For example, the "comfort" changes made to the SuperSix or Emonda SLR don't seem to have hurt the weight at all. Maybe they could've shaved another 20g, but that's very hard to say. Bianchi's CV technology probably adds a few grams to the frames, but since its really just an extra few layers in layup its not much. The elastomers, pivots, etc will all add weight, but really you're talking about ~100g total, so unless you're running full DA/Red/SR and carbon tubulars, there's plenty of other options to drop equivalent weight without sacrificing comfort & performance.
Pro level endurance bikes are still under UCI limits, and that's with power meters, computers, etc.
