Does Rails 3 eliminate URL helpers for 'show'???

I don't seem to have the usual *_url, *_path helpers for the show, update, or destroy actions on resourced routes. If I make a new rails app and add a route resources :random, I get url helpers for new, edit, index, etc - but not for the helpers that require passing a model instance.

Has this been changed in Rails 3, or do I just have something misconfigured?

The documentation for ActionController::UrlFor says the helper routes are *supposed* to be made, and I can still generate the routes using ActionController::PolymorphicRoutes#polymorphic_url - I'm thinking this is a bug???
