Truly impressive. I'd also like to see the Rails team focus on Rails-as-API for those of us who have moved on from the asset pipeline (splitting the server side from client side).

It would be nice to have a "API only" flag option when generating a new rails project. Something like: `rails new myapp -api`. This could keep Rails going for another 10 years.

I'm looking into using Napa, a Grape based API framework, for the purpose of Ruby server-side API apps: https://github.com/bellycard/napa

(Napa is to Grape as Padrino is to Sinatra)
