FWIW my take on this is that it’s a bug that wouldn’t have even been considered back when dyld2 was being used because the necessary infrastructure to even make these kinds of guarantees were not present. With dyld3/4 it has become load bearing since it has extra privileges under newer security models which consider non-dyld code to be less special.
