When I was saying "Such as?" I was talking about stuff like the Void Century and the Will of D., not standard plot elements like Devil Fruits, character motvations, and other stuff that compare to what you were listing about Naruto. There isn't really any major lore elements carried in Naruto until nearly end. Hell we really didn't get a whole lot of lore till Part 2 of the series.
As for Shanks losing his arm, it's heavily implied to be intentional in his confrontation with Whitebeard to "invest in the future." which again, is something being carried over throughout the course of the series and actually makes the series more interesting to read because it says there's something more. On the other hand, when Kishi explained the existence of the Sage of Sixth Paths, there was never anything left open and it very well could've been it aka a stopping point. This makes a lot of the lore elements feel hamfisted and made up on the spot in comparison. The only one he really did that with was with Madara.
Like phaze already said, I don't think we're arguing that Naruto has the quality/quantity of foreshadowing compared to something like OP but we're saying there are strong plot lines that stretch from the begging of the series to the end that that silly plot chart clearly ignores. If anything the Naruto chart should look like the OP one but less dense.
And that Shanks example is still silly sauce. Invest in the future all you want but I still don't see any reason for a man as strong as Shanks turns out to be to lose his arm to a creature Luffy one shots on his first trip off the island.
