WinRT C++/CX can use intrusive_ptr directly because it is native, but C++/CLI can only hold pointers to native objects because of the CLI.  intrusive_ptr is a direct alternative to the CComPtr template and COM interop, and only better when you want/need portability.. wouldn't expect MS to be interested..

You may not be aware that Microsoft contributed WinRT support for 
Boost, and that should be fully merged into Boost 1.57.
 
I'd suggest you hand over your idea to one of the Microsoft engineers 
on this list and let them push it for you as part of their general 
support of Boost. Search the archives for patches from Microsoft, you 
probably don't want Stephan but you will want Steve (stgates).
