Web technologies are not "suddenly" inferior to native technologies. They have always been inferior in some ways, and superior in others. Letting javascript run when the browser isn't even in use would sacrifice one of the ways that web technologies are superior (nonintrusive when not in use) to make it a little less inferior in another way (ability to set up background tasks). That doesn't seem like a good tradeoff to me.
