Also I remember reading (can't find now) something about default traffic quotas. I'd hope the default quotas are very large (infinite?) and not small so that compatibility is maintained. It would be very unfortunate if some of our traffic was throttled because of the upgrade because of magic defaults. For example we have a certain cluster dedicated to serving a single important topic and we'd hate for it to be throttled because of incorrect defaults.
