while such a thing would on the surface be nice, it wouldn't be nice for people coming to an area after you're done grinding on those najabs for example.
Say after you've killed them 10 times they now take an hour to spawn instead of 20 seconds. You've gained a level, which is what you're after, but the next person coming along can't find any.
Similar with kitins. Would be very easy to kill enough of them to trigger that invasion, then port out. Do that in a major digging area and you're preventing others from digging...
Such complications are probably among the reasons this hasn't been (fully) implemented.
