Chrome is not hiding the bar address, it is only showing the domain in normal times, and showing the full url when you hover the bar
Personally I find it better for non technical people, because they can focus on the domain only. For tech people you have the option to keep the full url visible at all time, which fixes the issue.
As for people complaining about AMP, this is something different, which has nothing to do with displaying only the domain, but instead "showing the real domain when you are on a google AMP page"
