Customer Addresses - Dependant on: {{ 'shopify_common.js' | shopify_asset_url | script_tag }} being included in the themes head. Not dependant on {{ 'customer_area.js' | shopify_asset_url | script_tag }} to avoid being restricted to just toggling visibility of address forms rather than opening a popup or anything else.
