default values of field not filtrable in REST API wp 6.0, acf - last

Added a field status with type select.
Set a default value as 'raw'
Set additional values 'html', 'cleared_html'
Added a filter

if( ! function_exists( 'post_meta_request_params' ) ) :
	function post_meta_request_params( $args, $request )
	{
		$args += array(
			'meta_key'   => $request['meta_key'],
			'meta_value' => $request['meta_value'],
			'meta_query' => $request['meta_query'],
		);

	    return $args;
	}
	add_filter( 'rest_post_query', 'post_meta_request_params', 99, 2 );

endif;

create several posts with default status = raw (i can see it in post data) but
wp-json/wp/v2/posts/?meta_key=status&meta_value=raw
giving me []
but if I update the default value manually (on 'raw' again), then filtering happens
this behavior makes the default value less useful and not always obvious in my opinion
Thank you!

Start by reproducing the REST request against posts whose select field has the default value raw, then inspect how ACF default values are persisted and how the REST post query handles meta_key and meta_value. Done means posts using the default value are returned by the same filter as posts whose value was manually reset.
