I add EAV attribute to a customer address.
I can use MagentoCustomerModelResourceModelAttribute $attributeResource to save the attribute.

According to Magento DevDocs https://devdocs.magento.com/guides/v2.3/extension-dev-guide/attributes.html

/** @var MagentoEavApiDataAttributeInterface $attribute */
$attribute->setData('used_in_forms', ['adminhtml_customer']);
$attributeResource->save($attribute);

It works.

I'm trying to use MagentoEavModelAttributeRepository to save the attribute.

The repository contains a method

 public function save(MagentoEavApiDataAttributeInterface $attribute)
 {
 try 
 /** @var MagentoEavModelResourceModelEntityAttribute */
 $this->eavResource->save($attribute);
 catch (Exception $e) 
 ...
 

and I see the attribute in eav_attribute database table but there are no records in the table customer_form_attribute.

Maybe someone can explain why?

Code example:

use MagentoCustomerApiAddressMetadataInterface;
use MagentoEavApiAttributeRepositoryInterface;
use MagentoEavModelConfig as EavConfig;
use MagentoEavSetupEavSetupFactory;
use MagentoFrameworkSetupModuleDataSetupInterface;
use MagentoFrameworkSetupPatchDataPatchInterface;

....
 /**
 * @param ModuleDataSetupInterface $moduleDataSetup
 * @param EavSetupFactory $eavSetupFactory
 * @param EavConfig $eavConfig
 * @param AttributeRepositoryInterface $attributeRepository
 */
 public function __construct(
 ModuleDataSetupInterface $moduleDataSetup,
 EavSetupFactory $eavSetupFactory,
 EavConfig $eavConfig,
 AttributeRepositoryInterface $attributeRepository
 ) 
 $this->eavSetupFactory = $eavSetupFactory;
 $this->moduleDataSetup = $moduleDataSetup;
 $this->eavConfig = $eavConfig;
 $this->attributeRepository = $attributeRepository;
 

 /**
 * @inheritdoc
 */
 public function apply()
 
 /** @var MagentoEavSetupEavSetup $eavSetup */
 $eavSetup = $this->eavSetupFactory->create(['setup' => $this->moduleDataSetup]);

 $attributeCode = 'test_attribute';

 $entityTypeId = AddressMetadataInterface::ENTITY_TYPE_ADDRESS;
 $setId = AddressMetadataInterface::ATTRIBUTE_SET_ID_ADDRESS;
 $eavSetup->addAttribute($entityTypeId, $attributeCode, [
 'type' => 'int',
 'input' => 'boolean',
 'label' => 'Test attribute',
 'required' => 0,
 'user_defined' => 1,
 'default' => 0,
 'system' => 0,
 'position' => 60,
 ]);

 $eavSetup->addAttributeToSet($entityTypeId, $setId, null, $attributeCode);

 $attribute = $this->eavConfig->getAttribute($entityTypeId, $attributeCode);
 $attribute->setData('used_in_forms', [
 'adminhtml_customer_address',
 'customer_address_edit',
 'customer_register_address'
 ]);

 // works. deprecated, I remember
 // $attribute->getResource()->save($attribute);

 // the attribute is saved, but the information on the forms in which the attribute is added is not saved
 $this->attributeRepository->save($attribute);
