Making a game mod friendly is a pretty challenging task IMO. I understand why its not a priority for day 1 because first it adds no value on day 1 generally, since it takes time for people to play and then design and implement mods. Second, if your game is barely getting over the finish line, as many AAA games lately seem to be, then you should probably have allocated those resources to making sure basic functioning is good before you add mods.

The engines often have most of the features already as they are used by the team when making the game.
Level, quest etc. creation isn’t generally done in code. So it’s likely there’s already tooling to achieve this.
Scripting of some sort is also often used by the engines to prevent the need for full rebuilds when changing things beyond the core engine components.
