A common thing that folks should "worry" about in Entra (or any platform really) is "who has rights to administer"? Who can delete or change key things, or modify them in ways that might not be obvious (accidentally or on purpose). Yes, we trust our people, but if they've moved on to other roles or to other organizations, they change from "our people" to "used to be our people". Also, it's common to have too many admins. For instance, entry level support folks might need rights to change…
