You did not miss anything. I just meant about starting discussion
about more flexible configuration.
BeanFactory/ApplicationContext is very flexible (see
http://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/beans/factory/config/ObjectFactoryCreatingFactoryBean.html).
And my worry is it is too flexible and the original flexibility should
be limited - as I listed in the cons.

Thanks a lot.
