It is easy for a person to do, but a program needs some crazy math stuff to do it. Bonus is it may be modified into Thaumcraft by Azanor as Pahimar was talking about sharing whatever the heck he's doing to help TC element values on items go dynamic, instead of the current "by hand" approach.
To be fair, EE3 is open source so by definition he is sharing everything about the mod. Azanor and Pahimar are in direct communication about all sorts of things though.
