I work in large Microsoft Shop that works with a lot of large enterprise customers. I doubt very much that anyone will start to say "Entra ID" instead of Azure AD. I firmly believe that for always we will continue to call it for Azure AD. Why? Because everyone knows what Azure AD is. The name itself is very descriptive in regards what Azure AD is (or the role it performs). "Entra" has no relation to anything and it sounds stupid also. This renaming is utter less pointless
