Sorry but I've not seen this approach done in any ruby gem I've used. Having to inherit from ActiveModel::Serializer just to do some configuration is not very intuitive. It feels like having to inherit from ActionMailer to edit SMTP server or inheriting from `class ApplicationModel < ActiveRecord::Base` and have my models inherit from ApplicationModel to change database connection.

I really don't mean to hurt anyones feelings, you probably have your reasons but I was left out of that discussion so voicing my opinion here and now instead.
