The problem with group DMs in slack is that they are almost always better off as a channel - you can’t really add new people to a group DM. So you’re forced to decide if you should make a channel or not right at the beginning. Group DMs can also have usability problems, and they tend to clog up the UI of slack. I currently have 5 or 6 group DMs going that all have at least one of the same people in all of them, so now when I use the quick switcher I see all of those. Some of them even have 2 of the same people in them - it makes it really easy to select the wrong group.
