Format Addresses in Uppercase
Postal Addressing standards prefer all lines of the address block to be in uppercase. I'd like to see this as an option or even the default for the address autocomplete, at least for US-based users

Format all lines of the address with a uniform left margin. Uppercase letters
are preferred on all lines of the address block.
