We recently had a wind storm here in the NW that kocked out power all around, a bunch of people, especially people for whom english was no their first language, died by running gennie inside the house, I think in one apartment building the death toll was over a dozen, hyperbaric chambers (needed for severe cases) were full in all regional hospitals... so I would have to agree that CO warnings are, ultimately, more important than electrical ones, in the short term
