My service worker shall support push notifications without a payload?

Question

I'm reading Mozilla's Service Worker Cookbook and I found that service workers implement event listener for the "push" event in two different ways:

1. Simply receive the payload inside the push notification event: https://serviceworke.rs/push-payload_service-worker_doc.html
2. Send a call to the server to retrieve the payload, after the notification is received: https://serviceworke.rs/push-get-payload.html

Why would I need to implement push notifications using the second options? Are there some browsers that don't support payload inside the push notifications?
