One of the figures in the article [1] adds something to this point: military engines have much shorter lifetimes. So it seems it's not just "trickle down" technology, there's also some redesign for reliability. A commercial engine can operate for a cumulative 1 year between overhauls, according to that figure, as of 2010. The military ones last 1/10th as long. I can only imagine how much more challenging it is to iterate on designs when you are dealing with problems that take 10 times longer to manifest.
