PHP-only block registration #73499

I try to register my PHP-only block with new auto_registration

and my code looks similar code example in doc, with small changes
I only add icon, category and title to register_block_type function
and after that i see my block in gutenberg (as plugin because API is new for now)

register_block_type( 'my-plugin/server-block', array(
		"title" => "My PHP block",
		'icon' => 'admin-generic',
		'category' => 'text',
		'render_callback' => function ($attributes) {
			$wrapper_attributes = get_block_wrapper_attributes();

			return sprintf(
				'<div %1$s>Server content</div>',
				$wrapper_attributes
			);
		},
		'supports' => array(
			'auto_register' => true,
			'color' => array(
				'background' => true,
			),
		),
	));

Question: As I see and suppose it's such function work (register_block_type) it takes title as "name" which first arg for function register_block_type and ignore it in second arg. Do we have any way to change it and for out PHP-only block change "title" for block without client side registation and without block.json OR I still need to add client-side script and set Title where?
