It's a good rationale. But it points the finger at a real bottleneck in open source development: the burden of manually reviewing contributions. And the need to automate that with AI as well. Reviews were already becoming a problem before AI. Lots of projects have been dealing with a large influx of contributions from inexperienced developers from all over the world looking to boost their CVs by increasing their Github statistics. It's the same dynamic that destroyed Stackoverflow. Which, thanks to AI has been largely sidelined now. And now that AI is there, those same inexperienced developers are using that at scale to generate even more garbage contributions.

Doing manual reviews of everything is very labor intensive and not scalable. However, AIs are pretty good at doing code reviews and verifying adherence to guard rails, contributor guidelines, and other rules. It's not perfect, but it's an underused tool. Both by reviewers and contributors. If your contribution obviously doesn't comply with the guidelines, it should be rejected automatically. The word "obviously" here translates into "easy to detect with some AI system".

Projects should be using a lot of scrutiny for contributions by new contributors. And most of that scrutiny should be automated. They should reserve their attention for things that make it past automated checks for contribution quality, contributor reputability, adherence to whatever rules are in place, etc. Reputability is a good way to ensure that contributions from reputable sources get priority. If your reputation is not great, you should expect more scrutiny and a lower priority.
