I said this on another thread somewhere, but won't be a huge loss for me as long as AA opens up nonzero transcon business saver availability once F is gone from the A321Ts. Being able to score F and FFD access for 25k MR transferred to Etihad is a great way to fly transcons - all made possible by last-minute Z saver award availability. However, I've never seen U saver space open up on a transcon since much earlier this year when I saw a few BOS-LAX-SFO itineraries bookable through AS.
