It wouldn't work as it would include in its scope methods that actually are not idempotent. This is because "the intended effect" of a request may go far beyond "the server". A method might be idempotent regarding the state of the server but not idempotent regarding other parts of the real world.

BTW the definition of "Safe methods" in the current draft is faulty for a similar reason.
