On one hand, almost every weapon type that exists in BG3 were weapon types that previously existed in DOS2. Those that aren't are more or less slightly modified versions of those that are.
Adding in new ranged weapon types like slings and darts would probably take a bit more resources than usual, and then there's also the question of what benefit they'd ultimately add to the game. From the most pragmatic standpoint possible... Not very much. You'd also eventually have to come up with unique weapons of those types, and then that brings up the issue of whether it's better to give those effects to already existing weapon types rather than risk the community not using said unique weapon(s) at all, simply because they aren't part of a weapon type that the characters specialize in.
Plus, as you've said, special arrows exist. Any new ranged weapon type is going to need something to match the ability to use special arrows. I wouldn't be surprised if javelins also don't make it in based on this principle alone, even though they're arguably the signature ranged weapon of Paladins.
Sorcerers missing those proficiencies reads a lot more like Larian deciding not to add them into the game, in the end.
