I like the way the ruling is now. I really don't want someones who doesn't know how to throw a racquet (read: Davydenko) to start throwing it around. It might hit someone because the angle at which he is throwing is way off. In that case, the racquet CAN hit a linesman and they might start bleeding (read: Gasquet, 2004 US Open qualies) . See, the consequences can be pretty serious... In the end, I just want to see tennis of highest quality being played.. that's about it. But as far as players, I think they worry about warning a lot more than some $500 fine. If they do it again, they might get a point penalty...
