I am not sure if you thought through the implications of your proposal. LLMs are trained on examples in the training material. If something is new and isn't accessible because it lacks tangible examples the adoption rate will be lower, so there will be less training material and therefore LLMs will not be of use here.
In fact, that entire aspect of LLMs is something that is not talked about as often. But is worth a whole discussion in itself. If I remember correctly, the availability of training material for a technology already has slightly impacted more niche corners of the tech world.
Software should still come with a documentation that LLMs can train on, plus they have all the learnings from interactions with developers asking about it - who will more and more just go this route (and following whatever guidance they get) and not thinking of searching for other material, let alone write guides for others. I'm not saying this is all that good, but that's the reasonable outcome.
