As a remote worker on an almost entirely remote team, we would benefit from a sort of voice channel huddle on-demand or even just watercooler chatting. There is something more casual about jumping into a premade voice channel where people may already be chatting than starting a Webex or initiating a Slack call that could introduce more "togetherness".
Something with this functionality was on my list when we were evaluating SaaS for our team and I really wanted something similar to Discord.
Of course no one would go for it as its branded, but having a forked version that doesn't bear any resemblance should be doable with minimum work.
