15 years ago the thing we call "web application" hardly existed. If web page "has nothing except JavaScript" (e.g. GMail) is probably is web app and indexing it makes little sense anyway. If someone misuses JS on content site, that's another story. And your comment about innovation makes no sense at all. Capabilities of modern browsers (Canvas, geolocation, local storage, offline apps, etc.) offer more opportunities for innovation than "old web" could even imagine.
