This thread seems like a storm in a teacup. From a data perspective addr:state is not really needed. Nominatim in particular and probably other geocoders as well assign it automatically based on state (admin_level=4) boundary relations. These relations are also tagged with ref=<2 letter code> which is why searching for something in "Manhattan, KS" works in nominatim just as well as "Manhattan, Kansas"
The addr;state field has generally been left off of address imports. Adding the field in iD to reduce user input errors might be nice and a good idea but the addr:state tag that results from it is of very little value.
