New Rails::API: Stakes and Opportunities around web applications and native clients

It is official since November 22, 2012, announcement from a group of Ruby on Rails developers presents to us New Rails::API.
For those unfamiliar, Rails::API is a derivative of the original Rails project that aims to provide a slimmed-down set of functions which are useful for developers using Rails to write applications that use a backend API-only servers.
Rails::API aims also to be useful for writing backends that can be shared between web applications and native clients. Therefore, it can allow a developer to create REST endpoints that accept data in JSON format and store it in the way a traditional Ruby on Rails application would.
This new subset of the Ruby on Rails feature set has had ActionView and other rendering features removed; this makes it easier and quicker to use for developers who are not concerned with writing frontends of web services and also makes the platform more lightweight.
