As someone who purchases domestic F on AA for the many of my annual flights, this whole situation is quite the bummer. From my home airport, CMH, both Delta and AA serve my most frequented markets with similar frequency and price. I chose AA when I moved back to the US due to (1) the 40"+ seat pitch versus Delta's lousy 36" pitch and (2) THREE 70lb checked luggages for all domestic F passengers. (3) A proper divider between F and Y (last row of F is very private).

AA got rid of the 3 luggages some time ago, and now they're getting rid of 40" seat pitch and the cabin dividers. The seats no longer have stuffing (ever since the change to leather seats).

I've been flying Spirit Big Front Seat on any nonstops with reasonable flight timing as a result of these changes. Just as ergonomic as the new AA seats. Frankly, the Admirals Club membership is the deal-breaker, but AA otherwise is hanging on by a thread (the pause in Oasis retrofits has allowed for proper seat pitch and dividers for most of my routes / flights).

I wish the US had a domestic airline with a proper F experience. I'd certainly pay a premium for it...

Comfy seats, a private atmosphere, proper meal service (8p and 900mi is a ridiculous cutoff), good service overall, and adequate luggage allowance would go a long way to increase the value proposition (and the fare I'd be willing to pay).
