The url is the enemy
All browsers are conflating the address bar and search into the one thing. The reason has less to do with usability and more to do with greed.
If the user types an unambiguous url then Google, Microsoft et al don't get an opportunity to deliver ads. So they'd rather users type a vague, ambiguous search term and then profit from ad keywords and ad impressions that appear in the results.
Thus the url is the enemy. Hiding the url or lopping bits off it is just an attempt to diminish its importance over time and increase the reliance on the search engine.
