I had thought that when dealing with smart pointers, one should in general 
always pass around the smart pointer and not the raw pointer behind it.  While 
you can reconstruct the smart pointer from the raw pointer here, there is 
still a point in time where you may lose access to the pointer if it goes out 
of scope elsewhere.  Thus I'd like to deprecate/get rid of the raw pointer 
version of that function.

However, I understand the frameworks are seeking to maintain source 
compatibility as much as possible.  I looked around on Techbase for some 
guidance, but I wasn't able to find any.  If such documentation exists, could 
someone point me to it please?  Otherwise, could some one outline it?
