I don't think that makes sense since the algorithm doesn't use
vector-vector multiplications and there is no need for them. As such,
you're actively excluding support for hardware which only provides
scalar-vector multiplication, even though that is all we need.

In fact, vectorizing the constant doesn't make much sense.
