He's a maintainer, gatekeeping is literally his job. He's the one who decides what makes it in or not. His reply is not great, but IMO posting to some venerable old project's ML saying, in the abstract and without actually having made any effort to analyze the issue in depth "Under what conditions would you consider replacing one of the current C implementations with an implementation written in another, "safer" language?" comes off as rather rude and not very productive IMO. I can understand him shutting it down immediately instead of wasting his time arguing with programming 101 students who cargo cult Rust without understanding the reality of maintaining something as complex as OpenBSD.
