In the 1.28.0 distribution, intrusive_ptr includes a non-explicit constructor and an assignment operator that take T*. This differs from shared_ptr, which provides neither. This is at best inconsistent and at worst dangerous. The danger is the same one that motivates shared_ptr to not deal implicitly in raw pointers; e.g. a function taking an intrusive_ptr can have an unmanaged pointer passed to where it can be unknowingly taken over by the intrusive_ptr.

Is there something unique about intrusive_ptr that makes it appropriate to differ from shared_ptr?
