Are there any reasons to hold off on taking the latest update?

Just in terms of eventual root, or something. It's not going to make much of a difference, or anything?

I'm on 6.O.1 - G930PVPU1APB5


Update G930PVPU2APD3

Its just that I notice it includes "security improvements," and that after updating, "returning to the previous version will be impossible. "
