I like the feature, but we also have false positive detections when using Jackson’s `@JsonSubTypes.Type` annotation (for an example, see [Jackson Polymorphic Type Handling Annotations](https://www.baeldung.com/jackson-annotations#jackson-polymorphic-type-handling-annotations)). Circular dependencies between base and child classes exist there “by design”.
