docs: We have to ensure consistency. If you listen on model events (e.g. `post.published`), you can expect that you always
  receive all fields including relations. Otherwise you can't rely on a consistent flow. And we want to avoid
  that event listeners have to re-fetch a resource. This function is used in the context of inserting
  and updating resources. We won't return the relations by default for now.
