I think this is really important to fix. 'Better communication' is something that I think would improve a lot of the friction around some of the process-ey stuff in the community. And you are right that communication between the sub-teams and the wider community (and in particular RFC authors) has sometimes been poor.
I'd like to see suggestions in this round of process updates for ways (formal and informal) to improve communication. I hope the increased pool of shepherds and increased level of interaction required to maintain the rolling updates will help. More ways would be better too.
