It's good to see you again, Mr Smith.There is a criminal system in the game that largely works in the way described in the most recent statement you shared. (One deviation I think is that instead of a guaranteed death based on crime rating it's a bit softer with corporal punishment being able to kill you if your health is low at the point of pummeling.)
Since the beginning of EA we have released any content that was ready. We have shared a blanket for a while longer now
The statements provide some insight on our current priorities (aka things we have been working on, are working on or will soon be working on). So using your example, we have prioritized party AI directives over marrying family members to companions.
Currently, such a feature is not approved, but I can bring it up at a suggestion meeting. I do think this falls more under polish than essential feature though.
Perhaps the matrix has fooled me again and I have seen what I wanted to see, just as the shadow is cast on the cave wall dancing gracefully with the fire.
