They are only needed for non-refcounted-things.  Compile time failure would be better, of course.

What you really want to check for here is whether the object has an AddRef and Release method.  I think the best way to fix this is to add an implementation of http://en.cppreference.com/w/cpp/types/is_member_function_pointer to mfbt/TypeTraits.h, and then static_assert your way to victory.
Bug 1307961 is a generalization of this.
