This "architecture" changes so much about Rails that I don't know why it's trying to build on Rails at all. If you don't like the Rails Way, just create another framework.
Yes, it replaces view rendering completely with Cells, but routing, dispatch, request serialization, activerecord, asset pipeline, rails-provided view helpers and more are all used basically as-is.
in short, since Rails 3 there is no "Rails Way"
