Should the linked issue be closed? Or left open?

If it was created based on a misunderstanding, it would be great to capture some of those details in the issue, and then close it out.

Once the issue is closed, we could then get this PR merged.

Good point @gep13. The linked internal issue is closed, but it looks like Unito didn't close the public one. I've pinged Paul on the integration, and will wait for him before I close the public issue.

With updating the issue with the misunderstanding, I have an idea, and have added it to our discussion meeting when I return from holidays. As such, I'll convert this PR to draft for now as I have some ideas that might lead to additional related changes here.
