   Just jotting down a quick comment that for the case of media / attachments, a server-side approach for registering fields for entities should also be able to support (or map) to the filter for attachment_fields_to_edit. I.e. for each field added via that filter, attempt to register an attachment entity field for DataViews/DataForm where possible.

   I've written that up in #75123 as it's not an immediate requirement for this issue, but will be for the media editor / registering fields for the attachment entity. So just something for us to keep in mind.

   Removed from the 7.0 project as this is not making it to WordPress 7.0 — we've focused on other features instead.

   I've started to work on this: added some initial tasks in the issue description, and prepared #76332 to bootstrap the server-side registration API.

   Here is a small plugin to test the fields API from PHP and a script module. It's tested on WordPress trunk with the Gutenberg build.

   It adds a Subtitle field to pages, stored in the demo_subtitle post meta:

   • wp_register_entity_fields() registers the field on wp_entity_fields_api_init.
   • The script module provides getValue and setValue, which read and write the value through meta.
   • The get_entity_view_config_posttype_page filter merges the field into the default Pages view and into the form.

   To test, add both files to wp-content/plugins/demo-page-field/ and activate the plugin. The field shows in Site Editor > Pages (list and table layouts, after resetting a saved view), in Quick Edit, and in the page editor's document sidebar, and editing it in Quick Edit or the editor saves the meta.

   demo-page-field.php:

   <?php
   /**
    * Plugin Name: Demo Page Field
    * Description: Adds a "Subtitle" entity field to pages, stored in post meta (Entity Fields API, WordPress 7.2).
    * Version:     1.0.0
    * Requires at least: 7.2
    */
   
   add_action(
   	'init',
   	static function () {
   		register_post_meta(
   			'page',
   			'demo_subtitle',
   			array(
   				'type'              => 'string',
   				'single'            => true,
   				'default'           => '',
   				'show_in_rest'      => true,
   				'sanitize_callback' => 'sanitize_text_field',
   			)
   		);
   
   		wp_register_script_module( 'demo-page-field', plugins_url( 'fields.js', __FILE__ ), array(), '1.0.0' );
   	}
   );
   
   add_action(
   	'wp_entity_fields_api_init',
   	static function () {
   		wp_register_entity_fields(
   			'demo-page-field',
   			'postType',
   			'page',
   			array(
   				array(
   					'id'            => 'demo_subtitle',
   					'type'          => 'text',
   					'label'         => __( 'Subtitle', 'demo-page-field' ),
   					'description'   => __( 'A short line shown under the page title.', 'demo-page-field' ),
   					'enableSorting' => false,
   					'filterBy'      => false,
   				),
   			),
   			'demo-page-field'
   		);
   	}
   );
   
   // Show the field in the Pages list and in the page editor's inspector.
   add_filter(
   	'get_entity_view_config_posttype_page',
   	static function ( $data ) {
   		return $data->merge(
   			array(
   				'default_view' => array( 'fields' => array( 'demo_subtitle' ) ),
   				'form'         => array( 'fields' => array( 'demo_subtitle' ) ),
   			),
   			1
   		);
   	}
   );

   fields.js:

   // The JavaScript parts of the fields registered in demo-page-field.php, keyed by field id.
   // The value lives in post meta, so it is read from and written to `meta`.
   export default {
   	demo_subtitle: {
   		getValue: ( { item } ) => item.meta?.demo_subtitle ?? '',
   		setValue: ( { value } ) => ( { meta: { demo_subtitle: value } } ),
   	},
   };
