When he writes about ohw StackOverflow is first and foremost a wiki, he is offering a solution to this situation. In the original vision of StackOverflow, that accepted and highly voted answer would be converted into a wiki. Then when it gets stale, it would be revised.

And ya it would be totally frustrating as a new contrib because if the canonical answer was not converted to wiki yet, you can't really contribute.
