I'm having trouble interpreting your message. Here are some possibilities for what I think you might mean:
(1) //sdk/fidl/OWNERS is out-of-date and doesn't match the current list of API councils members. We should update this list to be accurate.
(3) Given that we have the API-Review flag, we might as well include more people in //sdk/fidl/OWNERS (e.g., people who frequently make changes to many subdirectories) because the API-Review flag ensures that changes are reviewed by the API council in any case.
Can you help me understand the question you're asking? I'm happy to answer, but I want to make sure I'm responding to the question you're actually asking.
