Hello,
Shopware 6 is still under development and all previous and upcoming releases are Early Access Versions. Please also refer to our roadmap for more information https://www.shopware.com/en/roadmap/
Due to that, of course Shopware 6 does not have the feature set, that Shopware 5 has. If you miss a thing please open a issue ticket here: https://issues.shopware.com/
Best regards from Schöppingen
Michael Telgmann
