Sorry to ask this, but what other demands of a 'Normal Scope' are not fulfilled for @Singleton?
It's instances are pretty well defined for the singleton context, so it's not a pseudo scope in terms of the spec.
Proxying? 

For me the @Singleton looks pretty similiar to @ApplicationScoped. Where are the differences?
