When tend with no-op it could be this function below just doesn't do anything. It can be deleted instead for saving more gas

    // Example tend is a no-op which returns the values, could also just revert
    function _tend() internal override returns (TokenAmount[] memory tended) {
        revert("no op");
    }

2. Title : : Using short reason string can be used for saving more gas
