Comment:

 Closing for lack of feedback. Additionally, `unset()` is safe to use even
 when the array key does not exist.

 As for ensuring the method returns an array: The method already does due
 diligence by passing `array()` as the fallback to `get_option()`. Any
 additional database corruption would affect more than the Customizer, I
 think.
