Safari has hidden both https:// and .www/.m for a long time now. It used to (perhaps still does) allow users to change the behavior via settings, though not for the iOS version. (I wonder how is it with Android) I don’t think I ever felt the need to see the www on the address bar. So that move by Chrome doesn’t really bother me.
The only thing that actually annoys me in this, is that if I decide to eliminate the www. from my websites, Google will penalize them in rankings for a long time. It’s a pain to make such a move and Google will not make it any easier. They should own up to their decision that www. is irrelevant and make it easier for websites to drop it.
