Exported PHP doesn't register post_meta

I set up a CPT and two custom fields.
I export the setup as PHP to add directly to the functions.php of a theme.
When trying to use the fields with block bindings it says acf/field is not registered.
Therefore the standalone PHP is not fully working for all the things you might want to use it for in a FSE block theme.

Workaround (from Claude) was to add the following code to the functions that registers those two fields as core/post-meta.

Added benefit: they automatically show up in Block Bindings Attributes menu

would be great if the SCF plugin exported the complete PHP!

add_action( 'init', function() {
    register_post_meta( 'bio-scf', 'bioscf', array(
        'single'       => true,
        'type'         => 'string',
        'show_in_rest' => true,
    ));

    register_post_meta( 'bio-scf', 'linkscf', array(
        'single'       => true,
        'type'         => 'string',
        'show_in_rest' => true,
    ));
});

Here's the PHP SCF exported:

add_action( 'acf/include_fields', function() {
	if ( ! function_exists( 'acf_add_local_field_group' ) ) {
		return;
	}

	acf_add_local_field_group( array(
	'key' => 'group_69aef45532825',
	'title' => 'BioSCFgroup',
	'fields' => array(

	),

} );

add_action( 'init', function() {

	),
	'public' => true,
	'show_in_rest' => true,
	'menu_icon' => 'dashicons-admin-users',

} );

Start with the exported PHP in functions.php, tracing the acf/include_fields and init entry points shown in the report. Compare the generated field definitions with the register_post_meta workaround; done means exported PHP makes the custom fields available for block bindings without manual registration.
