The proposal for Chrome, you don't, because there's no stopping it. See DRM, Secure Boot, all the rest of the shitshow pursuing "trusted environment". It'll never happen, but CEOs won't accept reality.
You can, however, embrace the rest: eg. keep serving your own content on http (along with https), gopher for retro compatibility, and because they are less prone to break.
Keep using your current device for browsing, and whatever refuses to serve you either leave it for good or keep a spare chromebook for all the "services" you can't avoid to use, like banking.
I don't have a better route. It's a bit like streaming: if I want resolution above 480p, I use a Chromecast with Android TV.
