This change is unlikely to affect many users. The RegisteredReferencedTypes support was only added in v2.13.0.
The existing ScalaAnnotationIntrospector functions will remain in all v2.13.x releases but are deprecated as of v2.13.1. They are likely to be removed in v2.14.0.
The module instance is a better place for this state and the move is needed as part of jackson-module-scala v3.
