> Postmarketos clearly exists and works, EVEN if LLMs were absolutely perfect for speeding up development ten folds, is there any absolute moral necessity to use them?

There's no moral necessity, but if you want to survive as a project moving forward, you'll have less and less velocity compared to projects using LLMs, so you'll eventually shrink and die as a project, because less people will contribute to a project that gets less features and bug fixes.

I don't understand why these projects have such a strong "moral" stance of "no AI ever", and instead they don't deploy LLMs to automatically review PRs based on their own guidelines, so that if the contribution is valuable, it gets through no matter if it was written by an LLM or not.

I'm pointing out that their expectation of AI-free OS is pointless.

Because AI-assisted code is most probably already present in devices they use.

And I dare say that even for PostmarktOS:

1) There's no way they can prevent AI-assisted code to reach their codebase.

2) They will most probably change this policy in the future lest other forks/projects outpace them in terms of utility and they get reduced to a carriage in a car world.

Probably not and why would it need such constraint?

Not even humans can do that. Documentation needs to at least be reverse-engineered and understood before implementation.

I'm sure it could generate a decent device tree

Can you?
