The current implementation of checkDataFetcherNullness() only validates nullability for method return types, which fails to properly handle @BatchMapping methods that return Map<Parent, Field> (no other annotations).

As a workaround, I currently need to annotate @BatchMapping return types with @Nullable (e.g., @Nullable Map<Parent, Field>) to suppress these false positives.

Is there any plan to reduce these false positive warnings?
