This is actually pretty cool, very well developed technology now. Remember there was a time when the thought of a turbo charger was a scary thought from a maintenance standpoint. And yet look at whats Ford has done.

There has been cylinder deactivation for years already on the 5.3L and maybe other engines. There have been some problems with it though causing rings not to seat and high oil consumption. There are ways to defeat this current system which I would also do to prevent the possible oil use issue.
The 5.3 the issues you describe were inherent between 2007-2009. The issues were fixed for the 2010s. Some of the oil consumption issues were not due to the DOD but to poor oil flow design. My '08 has fouling #1 plug. The fix is to replace the valve cover with a redesigned one for that head. For $7 a plug, I just replace it every 6 months. And a quart of oil a month doesn't bother me in the slightest.
