 ###### Will enabling / using this feature result in any new API calls?
 
-No
+Yes, enabling this feature will result in a new HTTP endpoint (/flagz) being served by each component (including apiserver). However, this is not a Kubernetes API type or resource; it is a non-resource endpoint that provides component flag information for debugging and observability. No new Kubernetes API objects or resource types are introduced.
 
 ###### Will enabling / using this feature result in introducing new API types?
 
-No.
+No, this feature does not introduce new Kubernetes API types or resources. While the flagz endpoint uses a structured JSON response with Group/Version/Kind for content negotiation and consistency, it is not a Kubernetes API object and is not managed or persisted by the API server. The GVK is used solely to provide a predictable format for clients querying the endpoint.
