When beans.xml contains bean-discovery-mode="annotated" then:

  public class SomeFactory {

      @Produces

      public SomeClass someClass() {

          return new SomeClass();

      }

  }

doesn't register SomeClass with a @Dependent scope.
Weld forces me to add some scope annotation: @ApplicationScoped, @SessionScoped, @RequestScoped, @Dependent. CDI spec 3.3 Producer methods has examples without any scope annotations, so I guess it should be possible in Weld.
