Well, sometimes an end to a discussion is exactly whats needed. Sometimes. Like when theres literally nothing to do about something. Or the discussion is going in circles. Or when it would take shorter time to try it out in practice than have another meeting about the best way to implement it.

determine next steps, then table the discussion.

Doesn’t table in the discussion rather imply that they’re going to come back to it at some point. I feel like “it is what it is” ends any further discussion on the topic.
