(Note: I did not read the article so I can't speak to the GP's point, but this comment isn't really about the article.)

I don't think so. I don't think people are asking for all possible triggering scenarios to be covered. They're asking for people to take some time and consider how others (less privilege || victims of abuse ||etc.) might be affected. A trigger warning is essentially a heads up.
