A "proper" 100-400mm APS-C format lens should be smaller because of smaller diameter elements.
As mentioned the physical dimensions feel more like a full format lens. Again - the Leica 100-400mm is smaller thus they have tried at least. Technically "a brick" is certainly not a bad indicator in terms of optical quality - bigger tends to be better.
