There was --limit-sao, which provided a pretty nice performance boost without material quality loss when SAO was limited to only I and P frames.
SAO can definitely be helpful at moderate-low bitrates. But the x265 implementation has fixed parameters for SAO. Adjusting them some based on bitrate or QP or content analysis could make it a more reliable net benefit even at high bitrates and high detail.
