> My understanding is that defensiveness is a complex trait
Agreed. It's also what's called a "poly-genic" trait, one which is controlled by many different "genes."
However, acute sensitivity in any one of the traits could lead to hyper-defensive bees.
For example, overproduction of venom, leading to colony being alarmed more quickly, or hypersensitivity to odor, same effect.
