Not that I know of, but it also isn't really anything worth talking about imo. They added claud review as additional "eyes" on PRs (which already found actual bugs missed by maintainers) and added an AGENTS.md for the people using agents. They require disclosure of usage of agents (including which one) to know to be ready for the usually pitfalls encounted with them.

Like... they could say they entirely ban agents usage in their repo but how likely is that someone that wants to use them just doesn't contribute because of the policy instead of hiding the usage?

IIRC it also effectively is the same policy as the Linux kernel.
