Finally, Georges Stavracas saved the day by doing a clean implementation (including the necessary underlying plumbing) at the very tail end of the 45 development cycle! Technically we're already past UI freeze, but we got a freeze break.
The last part of the development was done on a stream yesterday: https://www.youtube.com/watch?v=XufZ_sa3u1s
Kudos to everyone involved in designing, developing, and landing this on time 🙌
