If we left that undefined the complexity of a move operation could be terribly varying depending on the implementation, and by consequence, unusable. In a container, for example, operation complexity refers to search and copy, but in node containers destroying values is orders of magnitude slower than doing a search. Information is power.
Information is power, but limiting the specification of an interface often makes better, more optimal implementations possible.
