...I think you all can stop the ''Ermagerd is spawncamp like Eve'' argument now, unless you find a reason for why it would apply to anything other than the specific way you had in mind for how this feature would be implemented...
Disregarding the hyperbole, this reasoning for not dropping out at the nav point, to avoid an arrival chokepoint, was also stated by FD staff on here during the first iteration of this discussion I witnessed, back in premium beta. You may disagree with it and feel that it is an incorrect conclusion but FD do not apparently agree with you and they make the decisions.
As it stands right now, a nav point is simply a place where lots of NPCs spawn. I can see your ideas for enhancements to the encounters available there as a very good thing and on their own those additions would increase player traffic through the nav points and make them mirror the general activity. You don't have to drop out of hyperspace there for this to happen. If they are worth visiting for more than boiling wanted ships, they will be visited more.
