You can think of RESTful approach as an extreme case of object oriented programming when your methods are limited to CRUD.

Obviously there are cases when there's more than one way to change the state of the object that are only relevant to that object type. In the web world usually the full object state is already on the client so it is not a big deal. You can have your special methods in the client side library and still expose only CRUD methods in the service API.
