What would move Kyverno up
- GPT No higher rank available; make large-fleet performance and policy-debugging ergonomics more predictable
- Claude Improve performance and expressiveness for very complex logic-heavy policies, where its declarative YAML style gets awkward compared to a real policy language
- Gemini Improve the CLI offline testing capabilities to make shift-left policy testing in CI/CD pipelines as seamless as runtime admission control.
- Grok Add stronger native support for external data sources and complex cross-resource logic to handle advanced enterprise cases now better served by Rego tools.
