Suggestion about Virtual Backgrounds...!

It's better if all Virtual Backgrounds in Zoom works like the Blur Effect. So, it only Focuses on the person who is in front of the camera. I said it because lots of Students use Zoom for e-learning at home. More than half of Students have only Desktop Computers. So, the Position can't be moved easily. If there is no suitable color to use Virtual Backgrounds, others can see everything, if he turns on the Video. Can you understand...? If the Virtual Backgrounds, focuses on the person in front of the camera, it will be better...! 

Thank you...!
