it isn't as before, before you could actually pick whatever robot you want to build and your own species wouldn't suddenly stop growing until all of your other species have reached the same population number, not to mention your other species would actually just grow on planets which they were present
its literally NOT the same as before
It's the same for me. Like I said, I wasn't ever big on dealing with that stuff in the first place.
If I'm playing the kind of game where I'm signing migration treaties, I'm not invested in what species mix ends up on any particular planet, or in the empire as a whole. They're all citizens anyway, right?
