That change creates multiple, distinct classes. shared_ptr<T,boost::checked_deleter<T>> is not the same as shared_ptr<T,my_deleter<T>>. By embedding the deleter in the shared_ptr with type erasure, shared_ptr<T> is shared_ptr<T> is shared_ptr<T>, regardless of the deleter.

None, unless I'm much mistaken.
