PERSONALLY I think the whole "Riot Gun" for home defense thing has gone the wrong way. Relatively speaking, we are easy to kill, even easier to hurt bad enough that we can't cause people any harm. You don't need a round that will go completely through someone when one that will only go half way through will get the job done to the same level of completion, namely STOPPING the threat to you or your family.
You are forgetting about the advertisement value of cutting an assailant in half with a single shot.
You can get the same job done with with a 9mm with better efficiency (if you aim well) as you can with a 12 ga buckshot. Yet, it doesn't create headlines like;
Spider Pig, a former Marine, Removed a Burglar From His Home by Turning Him into Pink Mist. That is some effective advertising if you ask me.
