If this were to happen, product teams would simply create more server-side fallbacks for their design patterns. All Javascript has done is make the web require fewer full page redraws. We'd be back into the days of server-side HTML rendering. I'm not sure that's a step forward. Stamping out a technology just because it enables a behavior you don't like won't stop the behavior. Meanwhile, you'll punish a lot of good actors. Video on the web, specifically, has a storied history, which is the bigger reason for what's going on with Smart TVs and how they relate to naked video files. Javascript has nothing to do with it.
