To be realistic and practical about it, I can see that including fold out plans is a waste 99.9% of the time. There was probably a time way back when where a representative amount of guys eagerly waited for the next plan to show up. I remember building from the 1/2 or full page size magazine plans, either transposing it myself, or going down to a blueprint shop. Nowadays we have Kinkos and you can spit out a 1 page plan for $5. I think having the plans available upon request makes sense, I would hate to think that 149,998 out of 150,000 fold out magazine plans go up the stove pipe.
