Not one bit. Traditional track bikes with round-bladed forks wouldn't have had brakes at all, so this would be a moot point anyway. But put a 200# rider on a "track" fork with round blades and a brake, and a "road" fork with oval blades, and with the same speed, braking force, etc., you'd be amazed at how much the front hub on the track frame moves "backwards" from braking force. I've seen it. It happens.
