According to a Twitter user, Albacore, the People Bar in Windows 10 may be making an exit. Some used the People Bar and found it very useful, while many others (myself included) turned it off. It wasn’t a bad idea, it just wasn’t useful for me at home or at work.
In the end, though, Microsoft has the metrics to show how used it was and if it was something that just didn’t justify the engineering manpower to maintain it.
In upcoming 19H1 Insider builds, the People Bar will show a deprecation notice. It's a shame to see something like this with rather interesting engineering behind it kick the bucket.
