There's been no communication that what you're describing is the case. A major goal of this update was, by their own words, to decrease micromanagement, and it has increased it drastically. Not sure what got lost in translation from concept to execution, but it seems like this is the direction they want the game to go in for the forseeable future.
At any rate, if they are planning on reducing micro, they haven't shared those plans.
To decrease mindless micromanagement. You don't just go by a planet and sweep upgrade everything, you don't just go through all your planets and do five hundred upgrades for every single new building technology you research.
But you do have to keep a constant eye on everything which gets overwhelming if you get to 20+ planets since you can't just queue up upgrades and plans in advance.
What makes things kinda bad in the long run is that pops don't stop growing but you can get to a point where you prefer that it does. The game actually severely punishes you if you let the planets go the way it would intuitively work.
This scenario has happened in almost every game I've played. I get a planet to a all districts spent, I don't want to urbanize since the planet generates base resources that I need so I just leave it at 0 housing left 0 jobs left.
When the next pop shows up it's unmeployed and homeless but the migration is weaker than growth so a new pop will show up.
By the time a third pop shows up the planets starts getting "Den of criminality" events
even though crime was at 0% and stability was 60/70+ prior to these events. I basically had no choice but to either
1) implement destabilizing decisions
2) constantly resettle
There was no option to subsidize migration, if I expel overpopulation
they leave my empire. There is just no good options for planets that are finished with development.
So you're forced to constantly babysit planets that in previous versions would've been fine to leave. You want to be able to leave a planet alone without it imploding. Attention and time are finite player resources, don't make the player waste time and attention on babysitting.
