I like this point because it's so hard to define "obvious". I agree they clearly are, but when LLMs are asked to pick the most important they tend to focus on a heuristic like "would show up in a summary", not creativity. Especially in longer texts like books where context is hard to keep they anchor on plot structure, for example time, rather than narrative.
