#default ⇒ Object

Some configurations use the ‘default’ key, like: gitlab.com/gitlab-org/gitlab/-/blob/c4d5c77c87494bb320fa7fdf19b0e4d7d52af1d1/spec/support/helpers/stub_configuration.rb#L96 But since ‘default` is also a method in Hash, this can be confusing and raise an exception instead of returning nil, as expected in some places. To avoid that, we use #default always as a possible internal key
