@DJPaul I know you have closed the ticket as won’t fix.
However, I’d invite you to consider this:
I think the functionality that we are after is “conditional” or “nested” fields. i.e. a list of states loading based on country selected.
The data (countries/states/cities/etc) need not necessarily be packaged with BuddyPress….maybe admins can load their own lists via csv etc…what’s important is the BEHAVIOR of the field…loading lists for a sub-field based on the value chosen for a field…
Come to think of it, conditional/nested fields could have many more applications than just addresses.
