Anyone intent on ganking newbies in preschool will just reset their gank-account CMDR after every kill. The first milk-run mission they take will still give them the money they need to make a ship that can pull over and down an actual new player's CMDR in a starter-tier ship in less time than it takes for the FSD cooldown of someone who didn't submit. Actually, selling the SRV bay, planetary landing suite, cargo racks, and shield gen on the starting ship would probably suffice.
I don't know what the motivation was for this newbie zone, but I cannot believe protecting new CMDRs from more experienced ones had anything to do with it, unless there were other radical unannounced changes.
