We have released 3×3 video for all of the Government clouds, on desktop and mobile.
We will soon bring Large Gallery view to Microsoft Teams, providing a new way to view video up to 49 participants at once on a single screen (7×7).

As a further enhancement, I would like to be able to set my profile to automatically always show the large gallery view when more than 9 people join a TEAMS meeting.
