Anonyme users automatic user group

It´s great there is now a possibility to have anonym users, but it would be even better, if all anonym users would automatically form a user group Anonym Users. Then you could allow the anonym users only to visit certain pages in your workspace. Now they are allowed to act as normal users. 

Thanks Lisa, so you would like to have a Anonymous user -user list automatically created.  Some further questions: 

1. Users in this list: should they have access to all pages as default or not
2. What happens if the users add his/her name after starting as anonymous user? 
3. Would there be a need for a user list: Everyone else except the Anon users
