Thank you for adding your suggestion to the doc~
It's much neater for us that way~
But to generally answer no.
We haven't considered it as mods don't use discord, and the group is generally supposed to be DeviantArt based, so mods do not have obligations to take care of group related things outside DeviantArt.
But if any member wanted to create a discord (or skype or any other chatroom) for the group, We wouldn't mind and we'd be happy to list it, so others can join in (via poll/announcement/link on front page), but anything that happens in there is not a mod's responsibility to monitor the chat or take care of it.
