Short answer is that they are working on an in depth environment/physical properties simulation system (confirmed by data leaks). Things like temperatures, flash points, coating in liquids, friction, etc.
It’s hard to know exactly how they will all be used, but one can imagine all the interactions between ice, fire, oil, gasoline, wind, and whatever objects you find in the world.

I hope we will see the fruits of that labour, not that I could afford a pc to run the eventual game.
