I'm not so sure, Tom. It took me a few minutes to deduce an answer from the page of code you linked. And I'm extremely clever! ;)
At any rate, in the case of a middleware class consisting of just a pass statement, at startup load_middleware will find and validate the existence of the entry in MIDDLEWARE_CLASSES. But since the class does not define any of the middleware methods, it will not ultimately be registered and therefore will not consume any CPU time when handling a request.
