What's the status about this? If we don't want to "break" the interface, 
  we can always provide an option to enable this feature, something like 
(same for scoped_array):

template<class T
#ifdef BOOST_SCOPED_PTR_ENABLE_DELETER
, class D = boost::checked_deleter<T> >
#endif
class scoped_ptr
{
// ...

public:
    ~scoped_ptr()
   {
      // ...

#ifdef BOOST_SCOPED_PTR_ENABLE_DELETER
      deleter()(ptr);
#else
      boost::checked_delete(ptr);
#endif
   }
};

BOOST_SCOPED_PTR_ENABLE_DELETER is not defined by default.
There are lots of samples like this in other boost libraries, is it 
reasonable?
