Form isn't just about the movement but strengthening your stabilizing muscle groups that keep your body aligned during that movement. By the time you start dead lifting serious weight, your core should be like a tree trunk and your muscles should be strong enough to support your body's alignment while flexed during the lift.
I do think too many people go overboard with the olympic lifts. You don't have to be red faced and shaking to get a good pump from a deadlift. Just because you can lift the weight in some way 5 times, doesn't mean you should. I bet most people who are boasting about their >400lb dead lift can't do that movement for 3x10 reps with good form. Lower the weight and it's as safe as the dumbbell squat.
