Hi, Sorry, I was not clear with my phrasing there.
While trying out a solution where a diverts transformer changes message destination, I discovered this was an issue (for my use-case). So the change itself really is about handling the case where a "computed" destination is missing (as well as a case where the forwarding-adddress has gotten auto-removed), as well as adding documentation on how to route/compute destinations through the transformer in a divert.
