our formal CAB sits with a different team, but have been working on similar things! our feedback loop is multifaceted and veryyyy v1. for example, we have a feedback channel, workflow only, and that gets funneled to the appropriate product team. ideally that becomes automated and more importantly, the loop get closed directly (i.e. this feedback was report in community and was addressed and shipped as a result of community).
but other tactics could be something like AMAs (workflow-powered) and office hour drop ins, in Slack.
does that help? are you looking for more solutions for this strategy (the tactics) or something broader?
