boost::static_pointer_cast for boost::intrusive_ptr (what SharedPtr is), takes its parameter by const reference. Given that, it means that this std::move doesn't actually do anything other than obscure what the function's actual behavior is, so we can remove this. To clarify, this would only do something if the parameter was either taking its argument by value, by non-const ref, or by rvalue-reference.
