Rails-api isn't a new project, and the name of the project is misleading. It provides a no-frills controller. Why is this is another project and not part of actionpack?
1. rails-api (the gem) forms the core. 2. ActiveModel::Serializers is now under the same organization, and making them work well together is a big priority. 3. Other gems/JS libraries may be built as we see fit, and put under the project umbrella as well. 4. I am now in charge of it all. ;)

Both of these gems were originally in HEAD Rails, but David reverted them.
Will serializers be in the Rails 4 Gemfile at least?
There _is_ a library called ActiveModel::Serializers in Rails 4, but it's much worse than the implementation that we have in the rails-api organization.
This is better as a separate thing. Maybe it could absorb the under-utilized ActiveResource subsystem.
