Though about this as well, but is there a real use case for this?

For a client proxy you might want to unwrap the current contextual instance . So maybe we should define two interfaces, something like WeldClientProxy extends WeldConstruct?

Hmm, as means to obtain metadata? Isn't it easier to just use BeanManager.getBeans() ?

For this you would need a correct bean type which is not always that easy to obtain.
