So, when the fixture changes, the loaddata call is happening again, right? I'll
assume this works as expected, i.e. replacing the data.

Indeed it does. Of course this is still not meant for maintaining the entire
database, it's more a bootstrap mechanism.

+        default => [],
+      }
+    }
+  }
+
+  create_resources(rietveld::fixture, $fixtures)
 }
