Not everyone wants to load those Mods, though. They are an ideal compromise between not wanting the developers distracted into adding content or features that might delay release or break the budget, and those who want the features included in the Mods to have them available.
I, for example, have no interest in playing a goblin so would prefer the developers to work on other areas. That said, I don't want those who really want a playable goblin to miss on what they want. Mods are a nice middle ground.
This is exactly why mods exist in the first place.
When the game is released, and if they are popular enough, Larian *could* put them into the main game. However putting them in now is a waste of time and resources imo. The game still needs to be made and completed.
