I wish this were true, but I think the opposite is the case: As soon as covid is really under control, the resorts are all open, and social distancing and mask wearing are a thing of the past, WDW is going to raise their prices, probably substantially, because everyone who hasn't gone in the past year--especially those of us who're feeling extremely Disney-deprived (that would be me!)--is going to want to go. There will be zero discounts. I hope I'm wrong, since this is probably when I'm going to go again, but Disney has been bleeding money and they're going to want lots of it as soon as they can get it.
And I'll be very surprised if paid FP isn't part of increased prices across the board for anything and everything. Even before covid, WDW had started charging for things they'd never charged for before--like parking at the resorts. And back in those golden days, they had plenty of income.
