Syntax highlighting is all I think they should do. If they want to color "http:" red to show that it's insecure, fine, but don't hide it entirely.

In 69, the version that just came out, they have begun to sometimes hide the subdomain. It threw me for a loop, because someone sent me a link to the mobile version of Wikipedia:

  https://en.m.wikipedia.org/

but the URL bar said just:

  https://en.wikipedia.org/

The page layout was very different, and I wanted to switch to normal. But at first it looked like I was at the normal URL and maybe Wikipedia had changed its look and feel overnight.

Thankfully you can disable this in chrome://flags, at "Omnibox UI Hide Steady-State URL Scheme and Trivial Subdomains." But this still doesn't bring back "http:"

Firefox too now hides "http:" but you can get it back in about:config, by setting browser.urlbar.trimURLs to false.
