Spawning Enemys
This is a big and complex theme. First I want to mention, that spawns are a the best cos endless source of income. As most other items are limited ingame and therefore money by trading, people may feel forced to start farming the spawns. As you don't know if you can use some loot again later, you will save it instead of selling it. The player will often just sell what the spawns dropped as he knows he has endless supply of it.
I also was confused by the fact that they always directly find me in the middle of nowhere. By this means hostility is actually 'thrown' at you what I didn't find very logical. Your are not glowing in the dark much, or having an "attack me" printed on my hull, how can they actual directly head towards me ?
That's why I thought spawns out of the gate start going on patrol first. They randomly change direction searching through space for enemy sovereigns. As you are an enemy too, they would attack on sight (maybe one LRS lenght). This could be shown by an "Enemy sighted you" - in this case you could try to run or face the enemy.
As more spawns pop out of the gate, the map would get filled too much !
To solve this problem problem the spawns are made hostile to each other too ! So it will happen, that you see pirates, fighting some anarchists, sapiens, whatever. So you may find more floating wrecks around and try to loot them - so salvager nomads would actually have a good job to do.
We must "destroy" the loot to. This may be acomplished by sending the spawns and filled salvagers back through the gate, letting stuff vanish in the data void.
This would apply to pirates too then - as they search for loot, they would also dock on their victims and as their cargo is much smaller, they would disappear soon again.
As this was the second most esteemed idea, I really hope you don't get me wrong. As you may have noticed, I tend to be a person who likes the vanilla game to be changed, as I have a somewhat negative mindset towards mods. I hope this post will not just disappear unchecked accuratley
