In our instances, we use both uiframework and addresshierarchy, so I don’t think that would be a problem on our end, however I can’t say for everyone, so it would be worth posting a new, separate Talk thread asked about this.
That being said, is there any reason you just can’t go directly to the Core message service? I forget off the top of my head what functionality “UiUtils#message” adds on top of the core messager service.
As for the design itself, I’d have to look deeper, but assumedly you will want to display the translations, yet store the codes in the person address fields? You’d have to have a way to map back from translation to code at some point, right? (Or maybe it’s not a complex as I think, I haven’t looked at the details of the module code in some time).
Take care, Mark
