   Roughly yes, but I think the way this concretely manifests is that if you call consume (or write) more than once on the same request/response, it returns a failure. However, as long as we have a single handle type, there's nothing stopping a component from receiving a request via call to its exported handle, consumeing this request, and then passing the same request to an imported handle function, thereby giving the callee a request that will fail when consumed the first time the callee tries to call it. If the callee is the host, the host would thus return a failure from handle. This breaks a logical contract, but, until we add back a handle representing exclusive ownership, we don't have a way to express/enforce this in Wit.
