That's interesting that you mention Project Managers, mainly because my experience has been just the opposite. We've been leaning much harder on those folks to manage the increased communication and coordination overhead that comes from WFH.
And this is certainly not to be directly contrary to your post -- which does raise a great point. In fact, it is many peoples' (warranted) criticism of and aversion to pointless meetings that helps me and my colleagues keep minimizing communication and coordination overhead at top of mind.
And everyone's interests tend to dovetail in this regard when these things are done well anyway: folks spend their time in meetings sparingly and efficiently, which in turn speeds up and makes more efficient the project/launch/program/whatever.
