Sure, I get what you're saying about those.
And this one is prying in just about any context, work or not:
> "Are you thinking about getting married, having kids?"
But these?
> "What did you do this weekend?"
> "What'd you think of the $SPORT game?"
> "Where are you going for vacation?"
> "Don't forget to vote!"
Those are just normal ways of making conversation! 99% of the time if someone's asking you this, they're not trying to get inside your brain and invade your privacy... they're just trying to talk to you. Honest question: do you prefer to have zero social interaction with your coworkers?
Edit: Also, it's bonkers to me that you think that this "has become" a thing. People have been making idle conversation at work since the dawn of civilization.
