One of the things I love about Drupal is the entity reference field. In Drupal 8, entity reference fields are even better because they’re now included in Drupal Core. This makes building composed and well-structured data much easier. However, I think as Drupal developers and architects, we’re fundamentally misusing them in far too many cases. Over and over, we use entity references to denote a relationship between two entities instead of a simple reference or inclusion.
