Selected speed with autothrottles in use is just defeating a safety feature that airbus felt you had to have because of the way they designed the autothrottle system.
True enough. However there are occasions when it can create more problems than it solves. I've seen many inexperienced pilots fail to appreciate the lower landing attitude which can be required and also fail to appreciate the greater elevator authority which the extra knots give them. The result is the inevitable over-flare, climb and drop-on well beyond the TDZ.
