This seems like a possible security/privacy flaw (also annoyance). In order to configure an extension it must currently be running. This leaves a window between when an extension is enabled, and when it is configured properly. If the extension comes with default configuration which could expose information, or allow abuse of the system, it would be possible to exploit during this time.
This seems to be done for a technical reason. Currently the admin configuration pages won't be loaded or accessible unless the extension is enabled. Fixing this issue might require a large change to the way extensions are structured or executed.
