In my experience, this comes down to the cohesiveness and experience of the group.Same here.
However - and I see this every week - when some players want to world-build (or the DM asks them to) and others don't, the inevitable result is that you end up with what feels like two "tiers" of players in the same game.
It's bad.
When I'm running game for newbies, I am happy if they can just come up with some backstory for their characters, and they seem very happy for me to do almost all the narrative lifting.
In my current home campaign, some players really like to build out the world in the context of their character. So last weekend, when one character finally revealed a huge chunk of her backstory it was news to me, even though it involved adding a new location, culture, and antagonist to the campaign. But she did it in a way that invited my collaboration, and it worked into the plot seamlessly, paying off a number of teases that had come before. We loved it.
On the other hand, my spouse barely has backstory for their character, and seldom does much world building beyond adding the occasional NPC encounter when their artificer is looking for parts and scrap. And they are happy with that.
A third player not only does substantial world building, but wants to take the reins for a story arc, as he has done previously (we'll see if it comes to fruition; I am the work-horse of the group, by far).
I don't get any sense of multi-tier players - it's just what everyone is comfortable with and enjoys. I think that is ultimately what all of this comes down to - figuring out the group dynamic that works so that everyone, including the GM, feels comfortable and included in the way that they prefer. There is no one way. I don't think there ever has been.
