It can still be fixed. And fixing it can lead to increased profits.

FFXI had a feature to address this issue (and the weakness of backing up from PS2 in general) where you could upload and download your hotbars and other information from the login screen by pressing a specific button combination. No need to overhaul the actual game engine, but giving people a way to back up and share their gearsets and character data via S-E's servers means more sales in the long run since playing on multiple systems will be less frustrating. I certainly don't bother the way it is now.
