Have not flown the A321 for a few years, but I also remember adding a few knots on the Approach page, to counteract this discrepancy, so that you could still use Managed speed for landing. (only if runway length not limiting). Before pigeonholing inexperienced pilots as the only people to get caught out, remember the two Captains at Bristol that scraped an A320 on takeoff. (too much sidestick input deploying spoilers).
