The primary advantage to encapsulating otherwise public data into

Yes,

One can change the value (if later computation is required) without
changing the interface. Resolution requirements change come to mind.
All said, how about the client specifying what he want.
template <class T>
struct IfToData //Or model from MVC
{
virtual const T& get( boost::void_<T> ) = 0;
};

....now the one getting specifies what he wants - his data now could
become:
boost::weak_ptr<IfToData<int> > myDataModel_;

This also makes him independent of the client from whom he receives
data...

It is a poor man's encapsulation, but it's still better than just
having public data fields.
