It's probably due to the fact that the game isn't finished yet. These are less important features you want to add when the game releases.
Although yes, hopefully they will be implemented.
Game companies tend to discard those great multiplayer features. Mainly because DRM means more money over quality of life. And you know what they say, money is what draw people. It's a good way to see what is the path a company is willing to take.
Sorry for the rambling.
