In order to minimise primitive obsession, I like to define my domain models with strong types down to the last leaf, e.g. record CustomerId(UUID value). When using these types as Mapping targets, I end up having to define a bunch of pretty pointless Mappers in this style:

@Mapper
public abstract class String2CustomerIdMapper {
  public CustomerId map(String value) {
    return value == null ? null : new CustomerId(value);
  }
}

What I'd love for MapStruct to do is considering CustomerId.class as possible Mapper via the uses attribute in these cases. Any chance we could implement this?
