You can approximate live fire scenarios in sparring. People get hurt and knocked out in sparring all the time, ask Chad Dawson. If instead of learning the skills, you just work out and have 3 fights a month, it's not going to work. You talk about mechanics unraveling under fire, but what's going to happen if you don't have the mechanics in the first place? I agree that you gain comfort and nuance from actual fights, but all the comfort and nuance in the world wouldn't have helped Gatti against Mayweather.
Any trainer using live fire gym warring is not running his sparring sessions right. Some of the best fighters I know got used up in the gym because of that type of work.
Mechanics are learned in the gym AND in live fire. You learn what works and what doesn't really quick when a big, angry, fat guy is trying to club you like a baby seal.
