"Hopefully, as with Activities, it will be possible to ignore it."
And, at least with KDE you can just link whatever you want into a directory (or a folder in KDE speak).
I was intrigued to see on the video something called a research feature or words to that effect. I take it it's Bing embedded into whatever application was being used. Good luck with that if you want to research a geographical location - all you'll get is bloody estate agents.
