irrelevant in what way? That you let nothing ‘bad’ in? Sure, you can do that, but increasing the threshold will also keep some ‘good’ out that you would have wantedKinda depends on where you want to go. If they are being conservative then they increase the approval threshold until it makes the systematic errors irrelevant.
Depending on how far you go, you are no longer improving in the direction the majority favors, you are only avoiding disaster. Some very clearly preferred options can still make it in, but the main goal at that point is avoiding mistakes, not making improvements
