AttributeClassDiscovery::$rootTwoLevelNamespaces

List of root namespaces abbreviated to two levels.

This list of namespaces is derived from the namespaces to look for plugin implementations in, with each namespace in the list reduced to the first two levels only, such as "Drupal\Component". Checking class namespaces against this list provides a way to check that dependencies' classes exist without using the "*_exists()" functions, which loads every class into memory and can throw errors.
