    "rationale": "Permissions to move subscriptions in and out of a Microsoft Entra tenant must only be given to appropriate administrative personnel. A subscription that is moved into a Microsoft Entra tenant may be within a folder to which other users have elevated permissions. This prevents loss of data or unapproved changes of the objects within by potential bad actors.",
