I believe they did remove the green lock from https sites to avoid implying trustworthiness. And removing the back button API is something Google can't decide on their own; it has to go through the standards process.

Nope. I'm on build 68.0.3440.106, the latest public stable build and as I'm writing this comment, little green lock and "Secure" right next to https://news.ycombinator.com.
Its a process. The green lock will be eventually removed, and instead of the "LOCK Secure" you see now, you'll see nothing, and http-only sites will be "Unsecure". This you can already see if you go to a non-https site like neverssl.com. There's a "Not Secure" banner in white.
