What it does
This resource model manages the database operations for customer form attributes in Magento 2.
It handles the storage and retrieval of attribute associations with customer forms, determining which attributes appear on specific customer-related forms (registration, account edit, etc.).
Developers use this class when they need to programmatically manage which EAV attributes are available in customer forms.
