This experiment didn't move relevant security metrics

And presumably did annoy the ### out of users who know what the address bar is for.

Just because you can, doesnt mean it's right.

i'll never understand how that was going to improve security.

phranque – subdomains!
On a smartphone the address bar is tiny and with enough subdomains the naked domain and tld are easily obfuscated — shifted to the right — and outside the visible address bar area.

ps: Safari had that domain feature for years
