support of federal units of Brazil with 27 states

...6.0.0.php

I see that in the native Magento2 is already pt_BR translation package, this was a breakthrough for users of magento in Brazil
I see that the support of the federal units of Brazil is not yet supported for Brazil, it would be very important if Magento2 added to support the 27 federal units of Brazil
Nowadays the form used to apply the support of the federal units of Brazil is done manually as shown below, and is usually done in the wrong way, because the need to implement proper support manual
