Rails default scaffolding and routing absolutely do use the full REST design, supporting both PUT and DELETE as well as inbound XML and JSON payloads

Sorry. I thought Rails had to make compromises, like faking PUT.

It fakes the PUT to help out browsers. If you pass in a _method paramater it overrides the actual HTTP verb, but this is actually done in middleware above Rails, the controller sees it as PUT.
