That's only useful if they plan to use location algorithms like banks to detect possible fraud login's. For example banks do basic location tracking to detect fraud, if you mostly shop in New York in a specific area and they suddenly detect a purchase in Canada your bank should block it, I know my bank does and they'll call me within 20 minutes to confirm it was me (enough time for me to call them and authorize it or if I switch to another card, quick enough for me to tell them I'm in Canada for the week.)
