Just love also the possibility do callbacks to the external IDPs, the possibility to extend the user journeys, languages localization and customize or deliver your own UI.
In the future I would also love if we could use a more modern work flow engine to extend the user journeys; making it far easier to support parallell «orchestration steps» and more visiual representations of the authententication and authorization flows.
Also the power to utilize and extend the conditional access and the graph api gives this external identity playform an amazing power to support the future requirements of modern identity solutions not only in Azure, but also in different clouds and in different OnPrems solutions. Built in the best interest of the identity holder and with the reqiurements of tenant owner: the CompanyID(entity).
