The strength of the 100% bond between the glass and the spar may not be required, although I'm certainly not qualified to determine how much less (if any) strength would be sufficient.
I suspect there are numerous builders who are like me - a bit scared of fibreglass due to total inexperience with it. Wing skins, where the quality of the work is important for both structural and aesthetic reasons strike me as a less than ideal place to learn. You say it's simple, and maybe you're right, but from the perspective of an absolute beginner it seems to me there could be a lot more work in getting it just so than some of the alternatives. Thus the attraction of materials like ply or aluminum.
