Consider, if you will, a modest to large group chat. Say a few people start chatting. dindingdingdingding People float into and out of the chat keeping it going for hours and notification after notification after notification comes in. Maybe they're in a group chat for several classes and/or interests and/or family. I can easily see it. I have to mute the group family chat I'm in when they really start to get going, especially my wife and sister-in-law.
