Hm, they might. Funny thing is I had been using the address bar as search bar (removing the search bar using customization) even since before it was really supported (it just happened to work, somewhat, unreliable). But I still hope they wouldn't do so as there are clearly situations where a combined bar just doesn't work well at all (like searching a URL or domain name in your search engine). And if I wouldn't be using mostly a laptop and 1080p24" monitor my setup might have been different.
