Limited? That describes about half the applications I've built in my career!

In all seriousness, there is a big difference between static content pages and full-blown applications; the cost to make the latter work properly without JS enabled is almost never worth it. But the same is true even for some static pages; for instance, I would never expect that NY times election forecast page to work without JavaScript, and don't see any reason that it should. (The "JS-based fakery" is pretty irrelevant to the discussion, IMO.)
