I don't know if we should use Scala Steward for Zinc since any change to version usually have some consequence.

I agree that I should have given more thought to this PR before approving it. That's on me. But I think the Steward PRs are valuable to have regardless, since they notify us when potential upgrades exist that should be considered.

In my opinion, it should work for zinc to have a newer scala-xml dependency than scala-compiler does, as long as the versions are binary compatible. (And unless it's too difficult to achieve, I suppose.) Let's discuss further on 7654
