Yes, exactly. Almost all computer games allow you to replay, and most have exploits, whether intentional or not. The goal for most game development is to cater for the widest set of playstyles possible, to encourage the largest player base possible.
That's why game series often change mechanics over the years, usually to simplify and broaden the appeal. Of course, that can be annoying if you liked the existing mechanics, but game development is a business, not a charity, so their reasoning is not necessarily the same as any given player.
In terms of BG3, I think that Larian's opinion is that they want to give you lots of things to do, and leave it up to you to decide what you use. I'm perfectly OK with that, although I recognise that there are a small number of choices that are not optional ( such as height advantage ) which can only be fixed by making that an on/off toggle; so I hope Larian consider making such mechanics optional.
The problem, is that Larian said from the outset, that they wanted to make a proper 5th edition DnD game, not a reskinned DOS clone, and they've done nearly just that.
At the moment, the game plays like you took a bunch of DnD characters, dropped them into DOS, and then told them that most of their class-specific skills no longer mattered or weren't class-specific any longer.
