Space outside of Lagrange points and gravity wells isn't attractive along any axis, the unstable Lagrange points have a plane which allows unstable orbits which have longer or shorter durations, depending on how exactly aligned with that plane the vector is. We should expect more junk, not necessarily a lot more, and this is of course simulated in the models used to design JWT... but not necessarily with perfect fidelity.
