Herald added a reviewer: NoQ.

Do *not* try to syndicate code across different location. Alhtough that would be benefitial to the project, it also makes this patch too complex and controversial because it would imply regression on some behaviors.

Instead, focus on compatibility with existing tests, and refine existing behavior wrt. bound size.
