nah....nothing wrong with putting unneeded stress on the motor and drivetrain.....
I'd much rather come to a stop with my brakes while in neutral which are a cheap and easy wear item to replace instead of constantly downshifting and revving down the motor, potentially causing damage to a more important and expensive driveline/powertrain part. Sure it may not happen, but each time you do, you run the risk of making a silly mistake. The more you do it, the higher the risk.
