IMO, just adding a comment is not sufficient and it might get missed by the gatekeepers/reviewers say, when the PR received many comments.

Not entirely sure. I think I remember there being some discussion about that on the original PR/some follow up commits. I agree that it would probably be good to make the workflow fail rather than just leaving a comment.

That should probably be done as part of a separate patch though.
