According to him, CF forks can lose up to 5% stiffness after thousands of cycles of high fatigue loading involving forces exceeding what is routinely encountered riding around.

And given that the CF frame is going to be stiffer to start, it's still going to be fine for years and years of riding. Pretty much a non issue as a practical matter.
