 You might have noticed that we didn't configure the schema registry URL anywhere.
 This is because Dev Services for Apicurio Registry configures all Kafka channels in SmallRye Reactive Messaging to use the automatically started registry instance.
 
-There's no Dev Services support for Confluent Schema Registry.
+Apicurio Registry, in addition to its native API, also exposes an endpoint that is API-compatible with Confluent Schema Registry.
+Therefore, this automatic configuration works both for Apicurio Registry serde and Confluent Schema Registry serde.
