Sure that's fine, although it would be good to also enable for fixed width-vectors, to make this more widely test-able. Another thing that would be good to cover is to vectorize with smaller VF than the input VF (something like `<4 x i32>` to `<vscale x 2 x i32>` or similarly, to make sure it is handled correctly)
