Say not browsers, but linux becomes the dominant OS in existence on all platforms, not just embedded and server. Does that move the most targetable platform back to the OS level instead of the browser level if we are going off the metric that human interaction and ease of use is more heavily weighted than all possible machine interactions?

Yeah probably, but there would still be the open question of distribution and update (inc dependencies).

You still have to click on the update button for a browser, and as far as apps on your machine go, they could just check for updates next time the application is launched like current web apps/web sites do. What you are saying is not impossible for the OS to take back. It seems more like there just isn't momentum to push browser features down the stack back into the OS and I'm not sure why other than browsers already do it, so why backport it.
