I don't see any point in having a sysctl for something like this: either you have legacy applications or you don't. It is not something that you switch off as you go off to lunch. A compile parameter, OTOH, would be too restrictive since it would force distros to choose just one behaviour (which would mean they would have to choose the most conservative).
