/**
 * Get all of the current attributes on the model.
 *
 * @return array
 */
abstract public function getAttributes(**$keys = []**);

I'm on holiday at the moment, is this something that can wait, or that you can submit a PR for?

I think it may be time to tag a new make version of this package.

This change has been reverted in v5.3.18: laravel/framework#15722

So nothing to do at this moment.

Thanks!
