According to a post on the Google Online Security Blog, beginning in January 2017 Google Chrome will begin flagging all sites that use traditional HTTP rather than HTTPS for passwords or other sensitive information as "insecure". It also indicates that Google plans to eventually start flagging ALL traditional HTTP-only sites as "insecure". While HTTPS has always made sense for truly sensitive information, a pure HTTPS web does have implications for legacy tools - essentially if anyone is not using the absolute latest of one of the "big three" web browsers, they will always potentially be just one security update away from being locked out of the web.

If rolled out after the vast majority of sites are already HTTPS, I could see it not contributing to the effect you're worried about.
That last 20% of http sites is gonna take a long time to shift. - run by people in their copious free time, on zero budget, with hosting companies that aren't falling over themselves to add Lets Encrypt support to make it click & drool (no, that's not always essential, but it makes it much easier, especially with Let's Encrypt's short-lived certs).
