Population_additive = false - whats your opinion?

What do you guys think of an idea of putting to every population zone such a line as population_additive = false?
Assuming that the order of zones in system.ini is coorect.

Is it a good/bad/neutral idea?
It will give patrols/tradelanes more chance to spawn I guess. That isn’t bad. Any comments, please??

Will try to do some tests now, will post results if any noticeable
