-----------------------------------------------------------

As already clarified with [~antoinesabot-durand] it is not possible to amend the behaviour of "annotated". 
But it actually *only* provides a benefit for bean-discovery-mode="all" as you will _not_ get interfaces etc for ProcessAnnotatedType if you use "annotated". Thus this new flag only makes sense in combination with "all". Which makes it basically an own sub-flavour and thus it's really the same like introducing a new bean-discovery-mode in the end.

> This is for some future CDI release.
> We currently only have 3 bean-discovery-modes
> * none
> * all
> * annotated
> The spec also currently says that ProcessAnnotatedType will only get fired (12.4) for 
> • each Java class, interface or enum deployed in an explicit bean archive, and 
> • each Java class with a bean defining annotation in an implicit bean archive. 
> • each session bean
> Which means that we do not get the ProcessAnnotatedType (PAT) event for any class in an 'annotated' or 'implicit' BDA which does _not_ have a bean defining annotation. 
> It might be useful to fire the ProcessAnnotatedType for all classes, but do not pick them up as Beans if they (after PAT) do not have a valid scope. Effectively doing the processing but not make them @Dependent automatically if there is no scope annotation at the end of the PAT processing.
> I'm not yet 100% sure how important this distinction is in practice. Just writing this up to not forget about the idea...
