> attach 10x length worth of AI appendix that would be helpful indexing and references.

Are references helpful when they're generated? The reader could've generated them themselves. References would be helpful if they were personal references of stuff you actually read and curated. The value then would be getting your taste. References from an AI may well be good-looking nonsense.

I agree wholeheartedly, I don’t see any balance in the effort someone dedicated to generating text vs me consuming it. If you feel there’s further insight to be gained by an llm, give me the prompt, not the output. Any communication channel reflects a balance of information content flowing and we are still adjusting to the proper etiquette.
