 In scenarios where you want more granular control than what `to_a2a()` provides, you may instantiate and pass an [`A2aAgentExecutorConfig`](https://github.com/google/adk-python/blob/main/src/google/adk/a2a/executor/config.py) directly to the `A2aAgentExecutor`. This allows you to override default data converters and inject execution middleware.
 
+### Suppressing Experimental Feature Warnings
+
+When you use experimental A2A features, ADK displays warnings. If you are knowingly using these features and want cleaner logs, you can suppress these warnings.
