That's one of the things I would really, really like to see.
But I doubt Larian will even do anything in that direction. Indeed, a lot of the Background things are roleplay, and they can't assume too much on a character without closing doors for the player's backstory for their character. Some of the things are more mechanical, like language and tool proficiencies. But Larian has removed these proficiencies from the game.
The two main things I'd hoping for :
- Dialogue options based on background. (Perhaps also a small, optional quest. If they have the resources to write one for the 13 official backgrounds.)
- Flexibility in choosing the two skills for our background. That's part of the standard customisation suggested in the PHB.
