I think we should take pride in our releases, so I disagree that it is
insignificant. If a maintainer is rushing things into late rc's and
breaking things then they need that feedback, not de-emphasize the
importance of ".0" releases. Could the bar be raised higher on late
fixes, perhaps. I otherwise think the message is already clear
"changes at -rc6,7,8 had better be worthy of and coming in late and be
accompanied with good explanation".
