Comment(by fmhess):

 One limitation of your solution: suppose I have private constructors and a
 static factory function for a class, and the factory function returns a
 shared_ptr.  If I make make_shared_access a friend, it opens a hole where
 people can still create objects of the class without using the factory
 function by using make_shared or allocate_shared directly.
