>Meetings are first and foremost about relationship management.

You might be hitting on a specific personality type, rather than a goal of meetings.

In his book “Never Split the Difference”, Chris Voss relates three kinds of people differentiated by how they relate to time. One group thinks of time as a way to manage relationships. That’s the manager you allude to. But another type is the classic Type A personality who views “time as money.” If the meeting isn’t getting to brass tacks and outlining strategy and tasks, they will be frustrated. The last group thinks of time as a way to wrap their minds around a problem to reduce uncertainty. The authors point is that you need to understand how people view the time spent discussing a problem to really know how to manage the interaction.

If you read many of the responses to your post in this context, it becomes clear which group each commenter belongs to in many cases.
