Likely helping more than fully officiating. Baseball piloted technology in the minors to accurately call strikes/balls. It did a better job than humans at making the correct calls, but everyone hated it because the robot umpiring made games last a lot longer. Like laws, many sports rules are subject to interpretation.
I do agree that the reviews in wrestling really slows down the action, for better or for worse. It was especially bad at NCAAs last year. Officials burnt a ton of time with reviews.
