Ah, it's because DL can only clear an upgrade to Y+ if the flight is DL-marketed or if it's within 24 hours of departure (at which point FB elites are unlikely to clear). Of course, what's a benefit to the Platinum (and maybe even Gold?) is a detriment to those who want UXP.
One wonders if it's possible to display both codes.
