Although I agree with what you are saying, this is hardly new. (And still disappointing IMO).

Developers in the RoR community have a tendency to say that "Rails is very good for one set of problems (Basecamp), and using it for anything else is problematic". This has been the answer for every attempt that tried to introduce some worthwhile idea to the Ruby community, be it OO design, TDD or something more "enterprisey" like hexagonal architecture. It's not the Rails Way™, move on.

I've heard developers whom I respect (ie. Avdi Grimm, Sandi Metz) shrug this inherent limitation of Rails off, and I find it really weird. It's akin to Stockholm syndrome really.
