The "contributor poker" made by someone on the Zig core team is a good one. You're thinking from the perspective like yourself and how they might be affected negatively by this policy. The org is thinking about what's happening at scale and what policy is going to improve outcomes overall for them.

Are there some potential contributors who might be discouraged because of this policy? Probably. Will maintainers have less time wasted by obvious low effort changes and engagement? Also probably. A user of AI is, in the experience of many maintainers, way more likely to be lazy than engaged.
