Any chance to reduce fuel consumption is a win.

  Not necessarily. Another commenter on this subthread found that the weight savings equate to 1-3% of total take off weight (fuselage, engines, fuel, people, cargo). There is a safety benefit to having windows (inspecting in-flight damage to aircraft). Is 1% weight savings enough to remove a safety feature? I don’t know the answer, but it certainly isn’t a clear-cut win.
