Hi John
I know in general from reading this thread that it is a very complex issue that will probably not be solved any time soon. What I was referring to was the rather “simple” thing you mentioned of deleting all values in specific fields upon deleting the fields themselves in ACF. You made a useful action for this, but there was a the issue of fields with the same names getting deleted in different groups. That made me wonder why this was an issue if the fields had unique identifiers. 🙂
