That's not the "certified" state either and you haven't expressed concerns about it.
Having a third AoA sensor to fail functional with one failure is a feature the regulator could require from all transport aircraft built after date XYZ.
Would that improve safety? Maybe.
Still arguing that it's a non certified state is bogus.
When a system fails, some degradation can be declared acceptable.
