To understand, the meaning of tenant scope, see my previous post on scopes in hybris. With version 5.0 , hybris decided to deprecate tenant scope.
In verion 5, Hybris has tenant specific application contexts. So the bean you will get will be singleton by default, which is already limited to a tenant. So there is no need to have a different scope called tenant.
As you can see fro above picture, each tenant creates its own set of application context, so now tenant scope is redundant.
