Just because something good isn't super awesome doesn't mean you shouldn't do it, and data like this would be extremely useful to people who are looking to make characters.
No, you don't understand. We know nothing. All we would have is, like, 3 materials with stats, and everything else would say unknown. It's a ton of extra work and there just isn't much of a point.
But like I said, we don't have any exact numbers. CK hasn't come out and said: "Endersteel armor gives X amount of armor." Most of the (non-vanilla) weapons/armor are made out of more than one material, which makes it impossible to make specific stats for a single material.
