Since 1.2 you can get meta from any bean and find it
if needee but i most of cases the context will see the bean and will not
need it.

Sorry for my brevity. Was on a cellphone only.
My point is: Context#get(Bean<T>) and Bean<T> only has getScope() which
looks like
public Class<? extends Annotation> getScope();
Thus having something like
@RequestScoped(allowMultithreads=true)
public class BlaBlaController {..}
would get represented by a Bean<BlaBlaController> which could only return
RequestScoped.class.
There is simply no way to return the
"allowMultithreads=true" information
somewhere as we only deal with
Classes.
The same applies to BeanManager#getContext():
public Context getContext(Class<? extends Annotation> scope);
Not related to me since the context should handle it and not the bean
manager.
No Annotation but Class, you see?
-> Currently there is no way to evaluate an additional attribute on a
scope
annotation.
And thus section 2.4.2 of the CDI specification also clearly states
"A scope type must not have any attributes. If a scope type has
attributes
non-portable behavior results."
