The BMEP of this engine at peak torque is about 188 PSI, which is very low compared to most current turbo engines, which are upwards of 432 PSI in the M-B AMG CLA45. That's 2.3 times the cylinder pressure. If the load delta was the culprit, then those engines would be throwing pistons every time they lifted from WOT.
Two engine failures in an entire career, I'm sorry but that's not even enough data to correlate anecdotal evidence. It's an interesting theory but I'd need to see some repeatable data to give it a serious look.

+1! No motor is infallible, well, perhaps for LS6
The key here is the cause. Was it something as "simple" as a valve spring (as was a case with 02 LS6), or was it an internal component? Was it related to manufacturing, or assembly process? Etc. Vintage, if yours is indeed the first failure: have patience as GM has to figure it out and that takes time. BUT, they should be treating ya with golden gloves regarding client satisfaction. NB when that guy's GT350 erupted in flames while ON TRACK, Ford (apparently) replaced it with a new GT350R. Not a bad outcome....
