## Summary Restore the established `AlterConfigPolicy.RequestMetadata.configs()` behavior for incremental DELETE operations. A DELETE of an unset topic configuration is omitted from the policy map because it generates no config record. A broker DELETE remains present with a `null` value, including when the broker configuration is unset. This preserves the KRaft behavior that the ZooKeeper compatibility flag introduced by KIP-1252 was designed to match. The Javadoc now describes the record-based behavior. Exposing deleted keys independently would require a separate public API proposal. ## Testing Updated the focused controller unit test to assert the policy arguments for an unset topic DELETE, a stored topic DELETE, and an unset broker DELETE. The test and Gradle checks have not been run locally. Recommended verification: ```text ./gradlew :metadata:test --tests org.apache.kafka.controller.ConfigurationControlManagerTest.testIncrementalDeletePolicyPreservesNoOpTopicBehavior ./gradlew spotlessCheck ``` -- This is an automated message from the Apache Git Service.
