Here's the 10 features:
1. Web Caching
2. Pagination with Multi-Page Navigation
3. Displaying Related Posts
4. Custom User Role Permissions
5. Social Media Integration for Popular Web Services
6. Site Statistics
7. Web Form Builder
8. Minification of Source Code
9. Better Site Search
10. Content Rating

Of those, 3 are already there, 6 are better served as plugins, and only a better search should be core code. IMO, of course.
