No, they said they aren't going to take backgrounds into account in dialogs and plot, because that's a lot of work plus taking away player agency. As in "That's how your character became a Folks hero".
No one said anything mechanics-wise so far.
That I am fine with cause they already have the challenge of accounting for spells, class, race, and other tags in dialogue and have taken on the challenge to give voices to corpses and animals. Not accounting for chosen background with dialogue I am fine with as a tradeoff.
