Who knows, perhaps they might add it as a feature in the future, in a similar fashion as they did the gift bags in DOS2 and call it; "Baldur's Gate Classic Party Size".

The only real reason I see on why they might not want to do it now is because of the valuable data they collect, which they use to balance and improve the game.

However even if they don't do it, luckily modding exists to envision what the devs did not wish to envision ^^
