Customizing the queue name & connection differs for listener and jobs

[rognales]

As mentioned in docs, here's for Listener

class SendShipmentNotification implements ShouldQueue
{
    /**
     * The name of the connection the job should be sent to.
     *
     * @var string|null
     */
    public $connection = 'sqs';
 
    /**
     * The name of the queue the job should be sent to.
     *
     * @var string|null
     */
    public $queue = 'listeners';
}

While this one is for Jobs

class ProcessPodcast implements ShouldQueue
{
    use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;
 
    /**
     * Create a new job instance.
     */
    public function __construct()
    {
        $this->onQueue('processing');
        $this->onConnection('sqs');
    }
}

Jobs do have the options to specify on runtime thru the same methods onQueue() & onConnection()

So my questions is, why do they differs? Any way we can standardize this? My use case is, to simply introduce a trait to customize these 2 props of all my related codes into the same queue.

Edit: Saw old thread on this but no clear reasoning #9869 (comment)
