Like Sawyer says above, this FEELS BAD. It feels bad to build a character who is supposed to be specialized in Persuasion and Deception, and helpless at Religion and History, yet find that you fail those social checks over and over simply because of the Tyranny of the d20, and yet somehow you're making all the knowledge checks because "lol, these dice man". At that point you don't even have a character concept. Who your character is and what they're good at is just randomly determined on a case-by-case basis, depending on the capricious whim of the dice.
Applicability to Baldur's Gate 3? Uh, I dunno. They have to do it the 5e way, I don't think it's something they can really fix. Unless they use some cheater RNG that doesn't actually model a d20.
This pretty much sums up where 5e failed, and what they should correct for the next edition of D&D.
Make the skills matter more.
Higher modifiers, rolling 3d6 instead of 1d20, there are ways.
If BG3 can't do that, what they could do is use thresholds rather than the d20 roll. Good old Take 10. Starting skill levels range from -1 to +5 and those differences need to matter much more. Only roll d20 when under stressful situations when it makes sense even the most skilled character can fail because of circumstances you can't control, or the least skilled can succeed because of adrenaline.
