Following CDI-642 and 643 I started to explore place where annotatedType can be used and where we don't provide access to AnnotatedTypeConfigurator [1], I really think we should solve this use case to avoid advanced users frustration discovering a new feature they can use everywhere (that was my case when realised that I could use it in BBD for Qualifier or interceptorBinding addition).

Possible solutions:

1) Add a hook to each of these place to obtain an AnnotatedTypeConfigurator

2) Add BM.createAnnotatypeConfigurator(Class) and BM.createAnnotatedType(ATC)

3) Add a Builder class that would provide a configure method

4) Transform AnnotatedTypeConfigurator into a Builder and simplify SPI using AnnotatedTypeConfigurator.

 [1] Non exhaustive list : 

- BeforeTypeDiscovery for addQualifier and addInterceptorBinding

- UnManaged class

- BeanManager createInjectionTartet and getInjectionTargetFactory or in InjectionTarget

- BeanManager getProducerFactory where a configured AnnotatedField or AnnotatedMethod could be useful
