Microsoft has stated they have no plans to allow role changes within default environments, therefore all users have the ability to create apps. When deploying PowerApps licenses to large tenants, it becomes difficult to manage the creation of PowerApps.
Currently we're able to view single app usage reports here, but there is no way to monitor tenant wide app usage, app creation, app sharing, etc. If we could get a report that summarizes these it would make PowerApps governance much easier.
The PowerApps Center of Excellence starter kit is a great way to get this information:
