Actually I think it is the other way around - since very few people would ever read commit histories - maybe if something really bad happened and we need to trace the audit trail ~once a month or something per team.

But LLMs can traverse that tree at will in seconds and mine valuable info. Commits description value in my experience has shot up dramatically _with_ heavy LLM usage - they are forgetful and commit messages are just the right place to keep “context that might be needed, but not worth adding to the documentation corpus” - they are the “how did we get here” to the “current state” of docs files and code comments.
