In my opinion this shouldn't be exclusive to Windows 10 Pro for Workstations and Windows 10 Enterprise. When connecting a non display device through HDMI (or another display connector) it will show up as a display and has to be used even if it doesn't have the ability to display content. (Audio receivers for example.) This feature would be a beter solution than duplicating the desktop to the in Windows listed receiver display and this scenario is probably common enough that limiting this to Pro for Workstations and Enterprise users will exclude a large group of users that would have otherwise benefited from the feature.
- Specialized displays. If you are running Windows 10 Pro for Workstations or Windows 10 Enterprise, you'll see a new feature called Remove display from desktop. This prevents Windows from using the display and makes it available exclusively for special-purpose apps that require it. This is particularly useful with medical imaging devices that have custom panels, video walls like those used in the Microsoft Store, and dedicated video monitoring
