Include Azure-AD delegation
currently it's only possible to delegate subscriptions or resource group, but this means we cannot manage our customers Azure services, such as Azure AD, InTune and Office365. So we still need an Admin account in the customers tenant. It would be of big help if Ligthouse can include the delegation to the whole tenant-level.

Also a lot can be done from Partner Centre though PAC delegated Partner Access - But yes all in all this would be excellent.
