The good: It doesn't have displacement on demand

Which is not an issue on this engine...The L8T is derived from the LT1 introduced in 2014. The 6.2/5.3 line of engines have the same DI with no issues due to carbon build up. It is was well know that it is not an issue on the GM V8. They also have a baffle in the valve cover to help prevent the problem, it reduces oil pull through in the PCV system.
In fact for some reason the GM vehicles don't typically suffer the carbon problems of certain other makes. See the GM 2.0 LTG turbo. I have one in the Malibu, borescope shows no carbon on the backside of the valves at 90,000 miles.
