The Rust team needs LLMs to adjudicate LLM-generated code properly, but they can't afford them (there is no money in OSS) and they are afraid of being put out of a job. Thus this Luddite policy.

I expect soon we will see Rust forks with a pro-LLM policy, and if those forks have AI agents reviewing PRs, the main Rust repo. will soon be irrelevant and all development of any note will happen on the forks, as they accelerate in quality and features exponentially. The Rust team will never be able to catch up to them.

> These are organized along a spectrum of AI friendliness, where top is least friendly, and bottom is most friendly.
