In the default permission configuration some settings are not available to Server Admins. You can add these permissions yourself using the ServerQuery interface.
These permissions are meant to be limited to the server owner. The permissions system is very flexible.
If you dislike the default settings you can adjust the defaults at any point by modifying the server template groups to your own preference.
The deployed default settings are what we consider useful. If you don't like these you can change them. Please see the permissions documentation for details.
