How big are the teams you've worked with? I agree it's productive for deep work and when design is already worked out for large changes or additions, but I've had many people on my team complain that they can't work through a hard problem on a whiteboard with peers or quickly sync up on a design and require more time in meetings to get things done across components/team members/teams. Also not everyone has a dedicated office space at home, those people are hurting and having a hard time focusing in many cases.
