You could insert using a std::move_iterator but this might not be as
simple as you want. You could also write your own wrapper over
std::vector::push_back to get a version that always moves:

template <typename Type>
void move_back(std::vector<std::remove_reference_t<Type>>& v, Type&& t) {
   v.push_back(std::move(t));
}

I could be wrong but I don't think there's a way to force a correct
compiler to select an rvalue-reference overload like this without
std::move or something equivalent to std::move. The exception would be a
case where the input is not an lvalue yet
(e.g., v.push_back(std::string{ "Hello" })). It seems to me that, in any
case, this would likely just be extra typing to achieve the exact same
result.
