Drupal utilizes the Symfony service container, however some features such as autowiring and autoconfiguration were not leveraged in Drupal 8. Since Drupal 9.3, services can be autowired. This means that when defining a service in *.services.yml, in many cases the arguments can be automatically inferred from the typehints on constructor arguments. More information on service autowiring in Drupal can be found in the

.
In order for other (custom) modules using services provided by this module to be autowired, aliases needs to be added for classes and non-ambiguous core interfaces (i.e. interfaces that only have a single implementation). It's not required for services of this module to use autowire: true, that would only be possible if the module only supports Drupal 9.3.0 or higher.
