Could you elaborate on what you mean by "compromised"? Sure, they can no longer be stacked 7 units high, but I am skeptical that cutting out a handful of windows and a door is going to make a container structurally unsound for the purposes of container homes. Cut out a whole side wall? That's a very different story.
