Is there any reason why additional Blu-ray/DVD content like later season Inside the Walking Deads/Making of The Walking Dead's haven't been added into the Specials listing?

Is it just a lack of desire to do so? Was there a debate somewhere in these forums but no consensus was reached?

If I did it, would anyone object? Just looking to have a comprehensive database with all of that extra disc content and if there are no objections I'll add it here based on what was pulled from the Blu-rays. The only thing I'd omit are the deleted scenes.
