Currently, when cloning the repository, 8.x-1.x is set as the default branch. Instead, 2.0.x should be set as the default. I am unsure about the default composer version for Drupal 9, since both 1.x and 2.0.x are Drupal 9 compatible. But of course, we should also set the preference to 2.0.x for Drupal 9, if not already done.
Enable 2.0.x to be the default branch
Fixed
