Caution: see https://www.drupal.org/project/drupal/issues/3086148

The name of the scaffold metadata key in the composer.json extra section might change this week. Friday is the code freeze, so whatever is in at that point will be stable.

See drupal-composer/drupal-project#522 (comment); all builds for Drupal 8.7.x and earlier will fail for a time.
