On: Don't write bugs

Then you've significantly increased the work (and opportunity for bugs) required of a downstream programmer, and also made it significantly more likely that they won't support all countries, and of course they could also still send the wrong type...

Plus, this stuff likely has to go into a database. Now we have polymorphic OOP stuff needing to be connected to records and fields in a table.

Maybe just have a generic "taxblob" fields which is a serialized object which indicates its type and all the properties by name.
