Bfold, I agree with you, and I'd probably give the same advice if the trainee were strength training instead of bodybuilding.
I would advise bodybuilders to avoid maxing out on deadlift, and also not to work near failure as form can get shoddy.
Also, the way the stretch reflex works is that the instant after you lower the weight (eccentric), the muscles produce force just by having been stretched, reducing the force the lifter must produce. So resetting a deadlift is similar to pausing with the bench press bar on the chest because they both interrupt the stretch reflex. That's the reason why spatts will approach the bar very quickly on a deadlift, it initiates a slight stretch reflex that can increase numbers.
