I'm already annoyed by the hassle it has become to copy a substring of the URL into the clipboard, due to the schemes being hidden. Nothing has been won by hiding http(s):// as well as the www subdomain.
Them acting like this is some kind of user experience thing is the most insulting part.
The URL bar is a disaster for end users. It's full of random junk that users can't read so they stop trying, which means they can then be tricked by phishing websites hosted on any domain at all. Research shows about 25% of users don't look at the URL bar at all even when typing in passwords, they navigate purely by sight, so it's impossible to stop them being phished. The human cost of the resulting hacking is significant.
The fact that the software industry has routinely prioritised historical inertia, the needs of web developers, and all kinds of other trivialities over the security of billions of people is embarrassing. I'm glad to see the Chrome team finally get a grip on this and make the URL bar actually useful for people.
