I don't think I've ever seen DHH or the Basecamp crew advertise any of this type of stuff as some groundbreaking new approach that nobody has ever tried before. On the contrary, I usually see them talking about how those old ways of doing web development were actually better in many ways, which is why they're pushing to move away from the current "everything is an SPA" approach.

And all this new tooling makes the experience much better than it ever was in the past.
