Would it be possible to have scopes behave in a usual CDI way ? I.e. you
should be able to inject a `@SessionScoped` bean into a `@Singleton` and the DI
framework should wrap it in a proxy and fail _at use time_ if the bean is used
outside of the session, but not at injection time.
> Allow Graphbuilder to use session scoped components

> Project: Maven
> Issue Type: Bug
> Reporter: Christoph Läubrich
> Priority: Major

> Currently DefaultMaven gets the Graphbuilder injected as a strict requirement
> at a very early stage. This leads to the problem, that a GraphBuilder
> implementation can not use any SessionScoped Components (because the session
> scope is not setup yet).
