Parser function

I'm wondering why CodeIgniter doesn't provide parser function to grab Parser Class , so we can use it directly anywhere without calling it as instance. 

for example:
before "as documentation":

PHP Code:

/* loading parser class through its service. */
$parser = \Config\Services::parser();
/* or loading it by instantiate it directly. */ 
$parser = new \CodeIgniter\View\Parser();

/* Then we can use it like this. */
$parser->setData($data)->render('index'); 


I wrote this function and placed it in app/Common.php, "actually just copy and paste"   system/Common.php view function and do some few changes to it.

PHP Code:

function parser(string $name, array $data = [], array $options = []): string
{
    /**
     * @var CodeIgniter\View\Parser $renderer
     */
    $parser = \Config\Services::parser();

    $saveData = null;
    if (array_key_exists('saveData', $options) && $options['saveData'] === true)
    {
        $saveData = (bool) $options['saveData'];
        unset($options['saveData']);
    }

    return $parser->setData($data, 'raw')->render($name, $options, $saveData);
} 


after:

PHP Code:

/* now we can use it in one short line. */
parser('index', $data); 


it's works as expected, so can it added officially to CodeIgniter 4? 

btw I couldn't pull a request on github it's so difficult there.
