People use iPads as laptop replacement with keyboard and mouse/trackpad, so interacting woudlnt be an issue for those users.
Dynamic Island would be great on iPad for extra on screen display of information, such as live activities, music app, timers etc can crack on with doing whatever you need a glance up to see the live infomation withtu having to change screens.
To change music you have to cover entire screen to access control center whereas dynamic island is a quick tap and doesn’t cover much content.
