It looks like an existing bug, as the synonyms are not actually being used. Therefore, it should pass true instead of false.

| ### Notable changes in 4.4.0 | ||
|
|
||
| * `kafka-configs.sh --alter --delete-config` no longer requires the specified config keys to exist on the target resource. Previously, attempting to delete a non-existent config key raised an `InvalidConfigurationException`. The deletion is now a no-op when the key does not exist, which allows managing configs for offline brokers via `--bootstrap-controller`. For further details, please refer to [KAFKA-20506](https://issues.apache.org/jira/browse/KAFKA-20506). |

Since this fix will be backported to the 4.3 branch, this note can be deferred to the PR targeting 4.3.

Ref #22070 (comment)
Remove the pre-flight DescribeConfigs existence check in
alterResourceConfig()since deleting a non-existent config isidempotent, and the check causes a timeout when the target broker is
offline.
