I propose to use traits here:

template<typename OwnershipPolicy>
struct has_destructive_copy
{
       BOOST_STATIC_ASSERT( bool, value = false );
};

template<>
struct has_destructive_copy<transferable>
{
       BOOST_STATIC_ASSERT( bool, value = true );
};

This way all other ownership policies no need to bother about notifying
framework about that.
has_destructive_copy could be made smart and try to deduce it's value from
the fact of present of appropriate constructor in argument type
