[cdi-dev] Should javax.enterprise.inject.Produces be inherited?

I think this is very problematic as you will get 
AmbiguousResolutionException all the time once we introduce this

I was just thinking about alternatives and producer methods.  Suppose I 
have the following bean:

public class Boop {

    public Simpler makeSimpler() {
        return new Simpler("Boop");

If I want to override the producer method, I need to declare fully:

public class BoopAlternative extends Boop{
    public Simpler makeSimpler() {
        return new Simpler("Boop2");

For some reason, scopes are inherited, but the produces annotation is not. 
 At least in the case of a producer method, it seems like it would be 
useful for @Produces to be inherited as well.
