Yes, I use also an extension that lets me type "w richard feynman". I also use DuckDuckGo, which has a lot of these shortcuts. But Safari will still offer the first "best hit", when I'm not sure where to look something up.
As for privacy, I'm already deep in Apple. They take care of my stuff: My entire Safari history (synced with iCloud), backup of my iPhone, my iMessage chat history, and a lot of other things. Given their stance on privacy, I choose to trust them. I've never accidentally pasted anything in the search bar.
