But what is this copper foil shielding in a specific part of the wing issue ? Isn't it standard practice everywhere in the plane, and what is so special and so costly about the leading edge ?
I think placement of conductive membranes and similar elements varies by location. Some parts of the aircraft, wingtips, radome, empennage, etc. are much more likely to receive lightning strikes than other parts, e.g., the fuselage. So more protection is applied to the more likely target areas. Not sure where, on that "scale," the wing leading edges fall.
Edit: I found this article in B's Aero Magazine:
