As things are right now, I see this as a respectable way of operating.
Michael has made his views and usage of AI known. The Ghostty project has a detailed AI policy for users to see and the team is willing to devote resources to enforcing a middle ground policy. The Zig project has a detailed policy taking a strict stance and as a result I expect they do not have expend as much resources when a contribution is suspected of being AI assisted.
A strict policy on either side is easier to enforce based on finite resources (mostly people). I'm sure many projects would like to have a middle ground policy but cannot currently devote the resources it would require long term. We might never see a shift in moderation abilities and this remains for the longer term, or there could be advanced in moderation that allows projects to adopt a more nuisanced policy that's right for them.
