AddressAdditionalData

What it does

This class provides a container for additional address data in Magento 2 quotes.

Developers use this model when they need to attach custom attributes or extension data to quote addresses beyond the standard fields.

It's particularly useful when integrating third-party shipping methods or adding custom address fields that need to be preserved during the checkout process.
