How to correctly listen on post-stream update

The solution for me to have decorateCookedElement run only once for a specific type, and when the last cooked content is ready, was as simple as that:

<script type="text/discourse-plugin" version="0.11">
  api.decorateCookedElement((callback, opts) => {
      if(opts?.widget?.dirtyKeys?.name === 'post-stream') {
          if(this?.cooking) clearTimeout(this.cooking);
          this.cooking = setTimeout(() => {
              console.log('All cooking is done, update new content..');
          });
      }
  });
</script>

Please correct me if there is anything wrong or there are any pitfalls in this code.
