I go along with my (ex)operator and agree with the philosophy of changing setting when first cleared to a FL/Altitude when climbing/descending.
In 99+% of occasions the clearance will not change, so to change when cleared makes sense and to deal with the 1% as the exception.
The OP asked about the A320, so I figured it was safe to make that assumption. In any event, you're right. Do current generation Boeings (apart from the 767) not have a feature that prompts you to change altimeter settings?
