the only problem with this is when the buyer decides to give negative feedback AFTER you have already given positive feedback for something that was the fault of the buyer to begin with, such as complaining shipping was too much when they didnt ask before bidding. This is the fault of the buyer, but they refuse to admit it and use the power of negative feedback to try and strike a blow.

by waiting till you see the customer is not going to pull a back stabbing maneuver before leaving your feedback as a seller, you are just giving yourself an ability to defend yourself.
