No chance. The whole idea behind both Android and Chrome OS is to push the user away from root access and leave Google as the one with root access on your device.

Except that you already can "have root access" and can "potentially run any linux app that compiles to ARM" today with ChromeOS and Nexus devices. In this very thread people are talking about running Crouton on chromeos devices and running Ubuntu Phone on nexus devices. In neither case do you need some kind of jailbreak to do so.
All that's needed for the GP's idea is for Android to take a page out of ChromeOS's playbook and allow a devmode that can run alongside of official Google Android.
There isn't a very meaningful distinction between "has root access" and "can get root access at any time by pushing out a binary update that your device will automatically install".
Nexus devices (i.e. the one with the most Google backing) can be completely re-flashed with a firmware that won't accept updates from Google's servers (e.g. with CyanogenMod). If you want an Android device free from their "imperialism", they've always offered one.
