I'll bet lots of climbs that follow cracks and corners have sections wide enough to place that thing. Since most of us don't carry anything that big, we don't even notice the placement opportunities.
Free association suggests the offwidth on Inverted Layback, the flake before the final overhang on the second pitch of Fat Stick Direct, near or above the sometimes-slung chockstone high on Double Crack, before the ceiling, perhaps on the right, on Bonnie's Roof, somewhere on Ventre de Boeuf and Last Frontier, low on the first pitch of Erect Direction, maybe on the corner on the left at the start of the second pitch crux of ED, and maybe also up in the horizontals above the roof on the third pitch of ED, up in the alcove before the slab traversing right on Boldville, the big flake high on the first pitch of Limelight, the short crack at the start of Proctoscope, in the flake leading up to Triangle, somewhere in the corner above the crux of Pink Laurel, etc. etc.
I could be wrong about lots of these; for the most part I'm recalling spots too big to hand jam. But just take the thing and you'll find places to get rid of it.
