1) I can't believe Airbus would get too worked up about "Remove status" rather than "Clear status". It has no impact on aircraft operation whichever you choose to say.
2) Setting trim according to CG was implemented over 4 years ago, so not really a new procedure (unless they've changed it back to up/down then back to CG again in the interim). IIRC from the time it was a Northwest 320 that had the trim incorrectly set and started to auto-rotate on the take off roll that led to the change.
