Nitpick: REST is very well defined. It's not just a protocol, like some people insist.

Other than that, fully in agreement.

Rest is effectively a concept, and its up to developers to follow the rules it sets.

You can't take your codebase, add some glue code to a REST module, and know that it will be usable by any other REST consumer/client, because no one follows the guidelines exactly the same way.
