Due to a bug in T410917 (r1234408), we accidentally caused T417195: Unexpected call to ConfigurationLoader::getTaskTypes when feature is disabled (February 2026) (an UBN). To avoid similar breakages in the future, we should add at least a basic integration tests coverage to this method.
The problem was checking for $geServices->getFeatureManager()->isNewcomerTasksAvailable() rather than !$geServices->getFeatureManager()->isNewcomerTasksAvailable() (inversed condition).
Fixing patches:
