LGTM

Although, when I read the documentation, it makes me wonder, do we actually use this? The scalar broadcasting makes sense regardless of if we allow this "dim-1" broadcasting or not, because scalars are essentially 0-D vectors. Nothing blocking on this PR though, we can discuss that elsewhere.
