Nope, nothing will; however, this allows the victim of ganking (like on tatooine) to defend himself to the point of where he has a chance.
I think that people are underestimating how strong that they will be when their 60 or 65 gets synced down. They will have all of their abilities, utilities and very good armor. Most players leveling up on that planet won't put up enough of a fight in PVP. As far as PVE goes, synced players will still roll over just about everything on the planet.
