Other common example from me:
```
struct SomeHeavyClass {};

std::unique_ptr<SomeHeavyClass> build();

void sendMsg()
{
    auto msgContent = build();
    Message msg;
    msg.content = std::move(*msgContent);
    send(msg);
}
```

And next one:
```
struct Info {
   virtual const std::string& getInfo();
};

struct
```

Simply moving a content of unique ptr is not an issue for me, coping big structure is.
User may want to move part of object from unique_ptr
