There are still cases where COW can beat move semantics. For example, I have need of the same integer in multiple places.
Then you should have all those places refer to the same integer, not make all those places hold a copy of it.
You could use boost::flyweight to achieve this. In any case it's somewhat you build on top of an object for a specific application, not a property of the object itself.
