You are right, in practice we need it. But practice is not enough, we have to keep in mind what's right too. And the right thing is to improve the built-in array ops :-)

And array ops don't replace everything you can do with a vector lib, you can define dot and cross product, small matrices, matrix operations, sparse arrays, truly rectangular arrays made of a single block of memory, etc.
