The pendulum swings both ways. Just like corporations decide to "centralize" and then decide to "decentralize".
Fashion comes and goes, only to return again and again.
The trend at this point seems to me to be simpler is better. Hard to argue against that. That pendulum will swing back the other way as well.
Many people take great pride in their very complex systems. All you need to do is look at the system pages to see that.
