This PR is unrelated to that discussion. I'm only adding this here to avoid adding new set of params to `isBroadcastableTo`.

I believe that before we commit to any new wider API, we should discuss the internal representation of `VectorType` and how scalable dimensions are represented. I am working on a proposal, but that's not yet ready to share 😅 I'm hoping to have something in the coming weeks.
