> It’s the language behind Kubernetes admission policies, Envoy’s RBAC rules, Google Cloud IAM conditions, and gRPC’s protovalidate<p>Very small nitpick, but AFAIK protovalidate comes from Buf, not Google. While protovalidate DOES work with gRPC via backward compatibility (but also Buf's ConnectRPC), saying "gRPC's protovalidate" probably makes people think it came from Google.<p>Disclaimer: I have no affiliation with either Buf or Google.
