The methods in these modules are not used anywhere. They used to beinvoked in polymorphic_routes.rb but their usage was removed ine821045.What is your opinion about removing these methods?They do belong to the public API, but in reality their code has already been duplicated to ActionView::ModelNaming, since they are used by methods like `dom_id` and `dom_class` to associated records with DOM elements (inActionView).Please tell me if you think that removing this module is a good idea and,in that case, if the PR is okay as it is, or you'd rather start by showinga deprecation message, and remove the module in Rails 5.1.
