Dynamic Office 365 groups

Would love to see dynamic Office 365 Group functionality without AAD Premium licenses! A dynamic group is great for areas such as when adding a new student to their respective graduating year "group". Or all students to a "All Students" group, new employee to an "All Employees" group, etc. Dynamic Exchange groups make this easy.

An as a side note, being able to "nest" the new Office 365 groups would make management of these groups much easier as well. An example is custodians, kitchen, office staff, all members of "Employees - Other", "Teachers - Middle School", "Teachers - Grade School", "Teachers - High School" groups all members of "Teachers", and Teachers and "Employees - Other" groups both members of an "All Employees" group. Works well with nested distribution groups or nested security groups, but I have to manage many more group members with the new Groups. A step back in manageability.
