It's an interesting video, obviously they have a dog in the fight so to speak. But notice the bolt/stud is coarse thread; you wouldn't spec a coarse thread anywhere vibration was a concern. If you look inside about any engine, where there is vibration or cyclic loads you'll find fine threads, usually without any locking means at all.
From fatigue point of view a course thread has larger profile radius hence a lower stress concentration hence a longer fatigue life. If the washers can guarantee the locking as the lower pitch of the fine thread does but in a different way..... Why not?

I can tell you that in the racing world we only use a nylock nut once. It is replaced with a new one after it is loosened. Personally I don't have an issue reusing a nylock, if it was not over tightened originally for personal use.
