Well, might not be nice but we cannot guarantee backward compatibility for such cases. CDI defines a contract. If you break the contract then the deployment fails. If we allow to break the contract then the contract is useless and we could allow anything...
Anyway what's the use case here? Is there a normal-scoped producer? I believe that having such a producer for a third-party type other than interface is not a good practice. Is there a normal-scoped bean class extending Hashtable? Not a good practice either. If so, the bean author should reduce the bean types by means of @Typed and allow the bean clients to only work with interfaces.
