I would offer it as an optional. When starting a game (and during the game) the player could be able to choose, if they want chances to be forced or not. Then everyone can have what they prefer.
Isn't that like D:OS2's Story Mode? Seems fair for folks that would prefer to not have a challenge and/or to build conversational skills up and simply want the story.
People expressing frustration towards this don't necessarily want an easier game. They just get frustrated by the bad streaks when rolling.
That said I'm personally glad that there's still more niche games that don't need to care much about this, as they don't attempt to cater to everyone. Big budget RPGs often tend to be action games with pretty light RPG elements to appeal to people who wouldn't necessarily even play an RPG, so kudos for Larian to at least not go that direction. When Larian had voiced last year that "missing wasn't fun" in D&D, I first had speculated that they may exclude attack rolls in their combat for this game entirelly.
