I haven't paid that much attention, but aren't the wings on most newer
airliners of lesser sweep than the first generation of jetliners?
Also, when were fences ever used on any jetliners? I can't recall
seeing them on, say, the 707. My understanding was that fences were
needed to minimize spanwise flow along wings swept back farther than
what you'd expect on anything in Pan Am livery.
