While we can certainly discuss whether the architecture is perfect (is there something like a perfect architecture?), I think it is beside the point. A fact is that a lot (most?) JSON-based services are built using such an approach. The simplest way to upgrade such service is to just add a couple of annotations. That's the functionality that the HydraBundle enables and that the demo app you reference above leverages.
