Android wasn’t designed with virtual reality or augmented reality in mind. This seems to be where computing is heading. Starting fresh with Fuchsia will allow Google to focus on virtual reality from the beginning.
In short, if a coding standard can’t be enforced mechanically (ie with a linter in the build), citing an industry standard, or referring to a group wide standards document it ought to be disallowed from a code review. That way we can all focus on finding bugs, logic errors, and security vulnerabilities.
