Controller Filters - Input needed

Just for reference for people who may be unfamiliar with Rails or PHP Middleware:

Rails / My guess of what CI4 would look like with Rails like filters

Code:

namespace App\Controllers;

class Companies extends \Codeigniter\Controller {
   protected $before_action = ['auth', 'cors'];

   public function index($company_id) {
     //This method will only execute after running the 'auth' and 'cors'
     //action set in the $before_action variable
   }
}

The filters/middleware I'm talking about has been in various other frameworks and talked about ad nauseum in blogs. Here are some links
