TYPO3 Core

The Changelog https://docs.typo3.org/c/typo3/cms-core/master/en-us/Changelog/master/Deprecation-94313-ClassAbstractService.html suggests in the "Migration" section:

"Please see `Service Implementation
<https://docs.typo3.org/m/typo3/reference-coreapi/master/en-us/ApiOverview/Services/Developer/ServiceApi.html#service-implementation&gt;`__
for more details about the required methods."

However if you have a look at this URL it states "All service classes must inherit from the base service class \TYPO3\CMS\Core\Service\AbstractService, unless the service type provides a specific base class (authentication services, for example, inherit from \TYPO3\CMS\Core\Authentication\AbstractAuthenticationService instead)."

It doesn't really make sense to replace the usage of the AbstractService by refering to the AbstractService once more.
