Hi Jie,
The dev mailing list is not of user questions! you should be susbscribed to the mailing list before sending emails to it, but please do not send this kind of emails there. This is the user forum where questions about the framework can be asked.
Yes to all your points, except the last 2.
13. User Management
This is usually responsability of an identity component, what the framework provides is integration with your identity component
and
14. Diversified client view
Not sure what you mean with this, can you elaborate?
