Same was true for me during AOS. Remember, each stage - AOS, ROC, Naturalization - they're all linked but really independent petitions. You cannot assume because you got approval before you'll have easier time with new petition. The whole immigration system is designed to test you multiple times before giving a new immigration benefit.
As I said, I'm more conservative and give all the evidence as instructions tell to avoid any possibility of USCIS requesting more. The other school of thought is "they already have it, why do I need to give it again?"
You can choose whichever works for you the best.
