Another way to think of things is consistency with primitive types. If
in your code you say

int i;
std::cout << i;

you will get some undefined output, since primitive types are not
initialized (except for file-scope static variables, but we should
probably avoid those anyway). For consistency

Vector3D i;
std::cout << i;

should do something similar.
