Hi,
For security reasons, one of the requirements we have seen in our customers are reltaed to the ablity to have more customized Admin roles. Some customers have different departments, that are responsible to manage the administration of some features independently. It's not fixed just with the Data Admin and the Admin. For example, some area needs to manage the Users and groups, but other area needs to manage the look&feel and white labeling, feature management... Now, an admin is a root user. And the Data Admin is restricted to Data Groups management.
Best!
